A computer is composed of two parts: a hardware system and a software system. Computer components generally refer to the hardware required to assemble a computer. Computer components can generally be divided into motherboards, power supplies, storage controllers, portable storage devices, built-in memories, and the like. These components form the hardware system of the computer according to certain rules. A computer consists of five basic components: memory, arithmetic unit, controller, input device and output device [1]. Computer components generally refer to the hardware required to assemble a computer. Computer components are the realization of the five basic components of a computer. The components of different types of computers are different, which is related to many factors, such as technology, craftsmanship, price and so on. Also known as the motherboard, it is the largest circuit board in a computer system. The type and grade of the mainboard determine the type and grade of the entire microcomputer system, and the performance of the mainboard affects the performance of the entire microcomputer system. The motherboard is equipped with control chipset, BIOS and various input and output interfaces, keyboard and panel control switch interfaces, indicator light connectors, expansion slots and DC power supply connectors and other components. They perform their respective responsibilities and closely link various peripheral devices. If the CPU is compared to the human heart, then the motherboard can be compared to the circulatory system such as blood vessels and nerves. With the motherboard, the CPU can control peripheral devices such as hard disks, floppy drives, keyboards, mice, and memory. The current motherboard structures mainly include AT and ATX structures, and the motherboards used by CPUs with different structures are not necessarily the same [2]. Some high-priced motherboards also integrate functions such as infrared communication technology, Bluetooth and 802.11 (Wi-Fi). Computer power supply unit (PC Power supply unit, often referred to as power supply unit, referred to as PSU or power supply), is a power conversion type of power supply for computers (different from battery-powered power supplies), which is responsible for converting standard AC power. Convert it into a low-voltage stable direct current for use by other components in the computer. At present, the general computer power supply is a switching power supply, and the input voltage automatically adapts to the mains parameters of the user's location (and some products may require the user to adjust the voltage switch). Many computer power supplies are also equipped with short-circuit protection, overload protection, overvoltage protection, undervoltage protection, overcurrent protection, temperature protection and other functions to ensure the normal and stable operation of the power supply and the equipment it supplies. Listed as an industry standard. In addition, some high-power power supplies will also be equipped with passive (passive) or active (active) power factor correction (PFC) technology, which has become an industry standard. Passive power factor correction is usually implemented by using an inductor-capacitor compensation circuit or a valley-filling circuit, and the power factor can usually reach 0.7 to 0.9; while active power factor correction is more complicated but can achieve a high power factor of up to 0.99. In order to control the heat generation of the power supply, there is also a lower limit of the power conversion efficiency, such as the 80 PLUS specification certification for informal industry certification.At present, the input voltage of the commonly used ATX specification PC power supply is generally between 100V and 250V. The latest ATX specification is ATX version 2.31 released in mid-2008. Common storage controllers have adapters, such as sound cards and graphics cards. Adapter (Interface Card, Adapter) is the communication bridge between computer and peripheral hardware, for example: screen, keyboard, CD-ROM, printer, hard disk, etc., each of which can only work by transmitting data through the adapter. Most computers now have built-in adapters, and external adapters are added if necessary.A sound card is an interface card used to process sound in a multimedia computer. The sound card can convert the voice, music and other sounds from microphones, radios, recorders, CD players (laser discs) and other equipment into digital signals for processing by the computer, and save them in the form of files, and can also restore the digital signals to real sound output. . The interface at the rear of the sound card protrudes from the back of the chassis, and there are interfaces for connecting microphones, speakers, joysticks and MIDI devices.Graphics card (Video card, Display card, Graphics card, Video adapter) is one of the most basic components of a personal computer.

C high-power long-distance wirele microphone module: The module is made of a high-frequency power amplifier on the basis of the A model. Because of the large power, it is neceary to match the better to exert its power. It is recommended to solder directly to the board with a 75cm rod or a 1mm thick enameled wire. [product ] Dimensions: 25*10mm Working voltage: 2V-5V (mobile power can be used, but with regulated power supply, mobile phone charger may have AC noise, if the voltage is too high, it will burn the launch tube) Working current: 30-80mA (measured input working current: 4.8V-87mA, 3.6V-63mA, 2.4V-36mA, test 80cm wire for the , respectively, using four, three, two BPI2100mah nickel-metal hydride test) Transmitting frequency: 80-110MHz (complete coverage of home FM radio frequency) Transmitting power: 150mw (C models), 50 meters - 800 meters (depending on the efficiency determines the distance) Receiving method: ordinary household FM radio receiving. The FM radio that comes with the phone can also be received, but the Internet app that the software APP requires network traffic cannot be used. We have a matching radio for sale. Emiion distance: The linear transmiion distance of the obstacles can reach 800 meters or more (6V power supply, 80cm profeional , Desheng PL606 high sensitivity radio test results, if the common or the obstacle group envment test in the building group, the distance will be shortened) 【product advantages】 1. Onboard microphone with external audio input (mono) 2. The input microphone and audio sensitivity are adjustable, and the transmiion frequency is continuously adjustable. 3. Transmitting power: 5v input can reach 150mw transmitting power, and the space is more than 300 meters! 4. All ed components, stable operation, frequency does not drift, hand touch does not drift. 5. Broadband modulation, super good sound quality, comparable to FM radio station sound quality. Precautions: 1, fever description: If the module is hot, it means that the is not very well matched. Some of the transmitted power cannot be transmitted through the . It becomes heat and will make the board hot. When this situation is found, it is neceary to consider adjusting the . 2. design: (1) The determines the transmiion distance. A good can transmit hundreds of times more than a few times more than a poor . (2) It is recommended to use 75-80 cm long, 0.5-1 mm diameter enameled wire, directly soldered to the transmitting pad on the circuit board, straightened and used vertically, the effect is better. (3) If the distance requirement is not high, but you want to be more subtle, you can use ordinary wires, which is shorter, but it will reduce the launch distance. Please test it yourself. 3, battery life: Many customers ask this question, you can calculate it yourself, the battery is different, the capacity is different, and the module works different time. Calculated as follows: 5v power supply - use time (hours) = battery capacity (mah) divided by 85ma 3.7v power supply - usage time (hours) = battery capacity (mah) divided by 63ma E.g: How long does a Samsung 2600mah 18650 lithium battery (3.7V) give power to this module? 2600mah divided by 63ma = 41.2 hours, about 41 hours, it is very power saving [C module - frequency debuing instructions] In the first step, ar the module is powered up, touch the rightmost triode to see if it has temperature (the fourth from the left, the volume is slightly larger). If it is warm, it means that it has started working. If there is no heat, the power supply is not connected. You can use a multimeter to measure the positive and negative voltages of the module. (A type of power is low, the triode is not hot, you can jump directly to the step) The second step, ar the first step is completed, ensure that the module is powered on normally, turn on the FM radio, turn to the maximum volume, adjust the frequency with the manual mode of the radio, search for 88-108mhz completely, and you should be able to find the frequency (the default factory default frequency is 96- Between 101mhz). Do not use automatic search. Automatic search sometimes skips the frequency of the module and does not stop automatically. In the third step, the above steps still can & #x27;t find the frequency. Don & #x27;t worry, you can fix the radio to a frequency without a radio station, such as 100mhz. Then use a 0.8mm extra-small non-inductive screwdriver (available in our shop) to tighten the frequency adjustment of the fine-tuning capacitor. It must be very slow to screw. When the radio suddenly has a sound, stop it, then use the radio to manually adjust the frequency. It should be just now. A frequency can be found near the fixed frequency, the sound is the most clear and the debuing is completed.

A computer is composed of two parts: a hardware system and a software system. Computer components generally refer to the hardware required to assemble a computer. Computer components can generally be divided into motherboards, power supplies, storage controllers, portable storage devices, built-in memories, and the like. These components form the hardware system of the computer according to certain rules. A computer consists of five basic components: memory, arithmetic unit, controller, input device and output device [1]. Computer components generally refer to the hardware required to assemble a computer. Computer components are the realization of the five basic components of a computer. The components of different types of computers are different, which is related to many factors, such as technology, craftsmanship, price and so on. Also known as the motherboard, it is the largest circuit board in a computer system. The type and grade of the mainboard determine the type and grade of the entire microcomputer system, and the performance of the mainboard affects the performance of the entire microcomputer system. The motherboard is equipped with control chipset, BIOS and various input and output interfaces, keyboard and panel control switch interfaces, indicator light connectors, expansion slots and DC power supply connectors and other components. They perform their respective responsibilities and closely link various peripheral devices. If the CPU is compared to the human heart, then the motherboard can be compared to the circulatory system such as blood vessels and nerves. With the motherboard, the CPU can control peripheral devices such as hard disks, floppy drives, keyboards, mice, and memory. The current motherboard structures mainly include AT and ATX structures, and the motherboards used by CPUs with different structures are not necessarily the same [2]. Some high-priced motherboards also integrate functions such as infrared communication technology, Bluetooth and 802.11 (Wi-Fi). Computer power supply unit (PC Power supply unit, often referred to as power supply unit, referred to as PSU or power supply), is a power conversion type of power supply for computers (different from battery-powered power supplies), which is responsible for converting standard AC power. Convert it into a low-voltage stable direct current for use by other components in the computer. At present, the general computer power supply is a switching power supply, and the input voltage automatically adapts to the mains parameters of the user's location (and some products may require the user to adjust the voltage switch). Many computer power supplies are also equipped with short-circuit protection, overload protection, overvoltage protection, undervoltage protection, overcurrent protection, temperature protection and other functions to ensure the normal and stable operation of the power supply and the equipment it supplies. Listed as an industry standard. In addition, some high-power power supplies will also be equipped with passive (passive) or active (active) power factor correction (PFC) technology, which has become an industry standard. Passive power factor correction is usually implemented by using an inductor-capacitor compensation circuit or a valley-filling circuit, and the power factor can usually reach 0.7 to 0.9; while active power factor correction is more complicated but can achieve a high power factor of up to 0.99. In order to control the heat generation of the power supply, there is also a lower limit of the power conversion efficiency, such as the 80 PLUS specification certification for informal industry certification.At present, the input voltage of the commonly used ATX specification PC power supply is generally between 100V and 250V. The latest ATX specification is ATX version 2.31 released in mid-2008. Common storage controllers have adapters, such as sound cards and graphics cards. Adapter (Interface Card, Adapter) is the communication bridge between computer and peripheral hardware, for example: screen, keyboard, CD-ROM, printer, hard disk, etc., each of which can only work by transmitting data through the adapter. Most computers now have built-in adapters, and external adapters are added if necessary.A sound card is an interface card used to process sound in a multimedia computer. The sound card can convert the voice, music and other sounds from microphones, radios, recorders, CD players (laser discs) and other equipment into digital signals for processing by the computer, and save them in the form of files, and can also restore the digital signals to real sound output. . The interface at the rear of the sound card protrudes from the back of the chassis, and there are interfaces for connecting microphones, speakers, joysticks and MIDI devices.Graphics card (Video card, Display card, Graphics card, Video adapter) is one of the most basic components of a personal computer. It is used to convert the display information required by the computer system to drive the display and provide progressive or interlaced signals to the display. , which controls the correct display of the monitor, is an important component connecting the monitor and the motherboard of the personal computer, and is one of the important devices for "man-machine dialogueKey FeaturesBrandName：qxgl RGB：NO ModelNumber：DDR31600MHz Package：Yes Origin：MainlandChina CoolingFin：No MemoryFrequency：1600MHz Type：DDR3 MemoryVoltage：1.35V Frequency：1600MHz Application：Laptop InterfaceType：240pinWhat's In the Box1*product

Turn it up clockwise and turn it down counterclockwise. Due to the large capacity of the output capacitor, the response will be slow when the output voltage is adjusted from high voltage to low voltage. The adjustment range of Jianyi is smaller. (the default output voltage is adjusted to 19v for shipment.) Current regulation: adjust the "a-adj" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the LED or current, and adjust the "a-adj" potentiometer clockwise to the current you need. For battery charging, ar the battery is discharged, it is connected to the output and adjusted to the current you need. When it is used for charging, it must be adjusted ar the battery is discharged (by default, the output power is adjusted to 3A for shipment. Do not adjust the current by short-circuit output. The circuit structure of the boost module cannot be adjusted by short-circuit, Input low battery protection regulation: low battery protection is mainly used to prevent the battery from over discharging when the input power supply is battery, and the low battery voltage will damage the power module and battery. For example, set the low battery protection of 12V battery. Connect a 10V voltage at the input end of the power module and use a slotted screwdriver to adjust rv1 (increase the protection voltage clockwise and decrease the protection voltage counterclockwise) until the UVLO light is on. At this time, the low battery protection voltage is 10V detailed list: 1*1200w boost constant current module 20A About shippingShipping and Packaging All it will be double checked and well packed before sending.It will be dispatched within 2 business days ar buyers pay for the order.

A computer is composed of two parts: a hardware system and a software system. Computer components generally refer to the hardware required to assemble a computer. Computer components can generally be divided into motherboards, power supplies, storage controllers, portable storage devices, built-in memories, and the like. These components form the hardware system of the computer according to certain rules. A computer consists of five basic components: memory, arithmetic unit, controller, input device and output device [1]. Computer components generally refer to the hardware required to assemble a computer. Computer components are the realization of the five basic components of a computer. The components of different types of computers are different, which is related to many factors, such as technology, craftsmanship, price and so on. Also known as the motherboard, it is the largest circuit board in a computer system. The type and grade of the mainboard determine the type and grade of the entire microcomputer system, and the performance of the mainboard affects the performance of the entire microcomputer system. The motherboard is equipped with control chipset, BIOS and various input and output interfaces, keyboard and panel control switch interfaces, indicator light connectors, expansion slots and DC power supply connectors and other components. They perform their respective responsibilities and closely link various peripheral devices. If the CPU is compared to the human heart, then the motherboard can be compared to the circulatory system such as blood vessels and nerves. With the motherboard, the CPU can control peripheral devices such as hard disks, floppy drives, keyboards, mice, and memory. The current motherboard structures mainly include AT and ATX structures, and the motherboards used by CPUs with different structures are not necessarily the same [2]. Some high-priced motherboards also integrate functions such as infrared communication technology, Bluetooth and 802.11 (Wi-Fi). Computer power supply unit (PC Power supply unit, often referred to as power supply unit, referred to as PSU or power supply), is a power conversion type of power supply for computers (different from battery-powered power supplies), which is responsible for converting standard AC power. Convert it into a low-voltage stable direct current for use by other components in the computer. At present, the general computer power supply is a switching power supply, and the input voltage automatically adapts to the mains parameters of the user's location (and some products may require the user to adjust the voltage switch). Many computer power supplies are also equipped with short-circuit protection, overload protection, overvoltage protection, undervoltage protection, overcurrent protection, temperature protection and other functions to ensure the normal and stable operation of the power supply and the equipment it supplies. Listed as an industry standard. In addition, some high-power power supplies will also be equipped with passive (passive) or active (active) power factor correction (PFC) technology, which has become an industry standard. Passive power factor correction is usually implemented by using an inductor-capacitor compensation circuit or a valley-filling circuit, and the power factor can usually reach 0.7 to 0.9; while active power factor correction is more complicated but can achieve a high power factor of up to 0.99. In order to control the heat generation of the power supply, there is also a lower limit of the power conversion efficiency, such as the 80 PLUS specification certification for informal industry certification.At present, the input voltage of the commonly used ATX specification PC power supply is generally between 100V and 250V. The latest ATX specification is ATX version 2.31 released in mid-2008. Common storage controllers have adapters, such as sound cards and graphics cards. Adapter (Interface Card, Adapter) is the communication bridge between computer and peripheral hardware, for example: screen, keyboard, CD-ROM, printer, hard disk, etc., each of which can only work by transmitting data through the adapter. Most computers now have built-in adapters, and external adapters are added if necessary.A sound card is an interface card used to process sound in a multimedia computer. The sound card can convert the voice, music and other sounds from microphones, radios, recorders, CD players (laser discs) and other equipment into digital signals for processing by the computer, and save them in the form of files, and can also restore the digital signals to real sound output. . The interface at the rear of the sound card protrudes from the back of the chassis, and there are interfaces for connecting microphones, speakers, joysticks and MIDI devices.Graphics card (Video card, Display card, Graphics card, Video adapter) is one of the most basic components of a personal computer.

At present, the general computer power supply is a switching power supply, and the input voltage automatically adapts to the mains parameters of the user's location (and some products may require the user to adjust the voltage switch). Many computer power supplies are also equipped with short-circuit protection, overload protection, overvoltage protection, undervoltage protection, overcurrent protection, temperature protection and other functions to ensure the normal and stable operation of the power supply and the equipment it supplies. Listed as an industry standard. In addition, some high-power power supplies will also be equipped with passive (passive) or active (active) power factor correction (PFC) technology, which has become an industry standard. Passive power factor correction is usually implemented by using an inductor-capacitor compensation circuit or a valley-filling circuit, and the power factor can usually reach 0.7 to 0.9; while active power factor correction is more complicated but can achieve a high power factor of up to 0.99. In order to control the heat generation of the power supply, there is also a lower limit of the power conversion efficiency, such as the 80 PLUS specification certification for informal industry certification.At present, the input voltage of the commonly used ATX specification PC power supply is generally between 100V and 250V.

A computer is composed of two parts: a hardware system and a software system. Computer components generally refer to the hardware required to assemble a computer. Computer components can generally be divided into motherboards, power supplies, storage controllers, portable storage devices, built-in memories, and the like. These components form the hardware system of the computer according to certain rules. A computer consists of five basic components: memory, arithmetic unit, controller, input device and output device [1]. Computer components generally refer to the hardware required to assemble a computer. Computer components are the realization of the five basic components of a computer. The components of different types of computers are different, which is related to many factors, such as technology, craftsmanship, price and so on. Also known as the motherboard, it is the largest circuit board in a computer system. The type and grade of the mainboard determine the type and grade of the entire microcomputer system, and the performance of the mainboard affects the performance of the entire microcomputer system. The motherboard is equipped with control chipset, BIOS and various input and output interfaces, keyboard and panel control switch interfaces, indicator light connectors, expansion slots and DC power supply connectors and other components. They perform their respective responsibilities and closely link various peripheral devices. If the CPU is compared to the human heart, then the motherboard can be compared to the circulatory system such as blood vessels and nerves. With the motherboard, the CPU can control peripheral devices such as hard disks, floppy drives, keyboards, mice, and memory. The current motherboard structures mainly include AT and ATX structures, and the motherboards used by CPUs with different structures are not necessarily the same [2]. Some high-priced motherboards also integrate functions such as infrared communication technology, Bluetooth and 802.11 (Wi-Fi). Computer power supply unit (PC Power supply unit, often referred to as power supply unit, referred to as PSU or power supply), is a power conversion type of power supply for computers (different from battery-powered power supplies), which is responsible for converting standard AC power. Convert it into a low-voltage stable direct current for use by other components in the computer.

A computer is composed of two parts: a hardware system and a software system. Computer components generally refer to the hardware required to assemble a computer. Computer components can generally be divided into motherboards, power supplies, storage controllers, portable storage devices, built-in memories, and the like. These components form the hardware system of the computer according to certain rules. A computer consists of five basic components: memory, arithmetic unit, controller, input device and output device [1]. Computer components generally refer to the hardware required to assemble a computer. Computer components are the realization of the five basic components of a computer. The components of different types of computers are different, which is related to many factors, such as technology, craftsmanship, price and so on. Also known as the motherboard, it is the largest circuit board in a computer system. The type and grade of the mainboard determine the type and grade of the entire microcomputer system, and the performance of the mainboard affects the performance of the entire microcomputer system. The motherboard is equipped with control chipset, BIOS and various input and output interfaces, keyboard and panel control switch interfaces, indicator light connectors, expansion slots and DC power supply connectors and other components. They perform their respective responsibilities and closely link various peripheral devices. If the CPU is compared to the human heart, then the motherboard can be compared to the circulatory system such as blood vessels and nerves. With the motherboard, the CPU can control peripheral devices such as hard disks, floppy drives, keyboards, mice, and memory. The current motherboard structures mainly include AT and ATX structures, and the motherboards used by CPUs with different structures are not necessarily the same [2]. Some high-priced motherboards also integrate functions such as infrared communication technology, Bluetooth and 802.11 (Wi-Fi). Computer power supply unit (PC Power supply unit, often referred to as power supply unit, referred to as PSU or power supply), is a power conversion type of power supply for computers (different from battery-powered power supplies), which is responsible for converting standard AC power. Convert it into a low-voltage stable direct current for use by other components in the computer. At present, the general computer power supply is a switching power supply, and the input voltage automatically adapts to the mains parameters of the user's location (and some products may require the user to adjust the voltage switch). Many computer power supplies are also equipped with short-circuit protection, overload protection, overvoltage protection, undervoltage protection, overcurrent protection, temperature protection and other functions to ensure the normal and stable operation of the power supply and the equipment it supplies. Listed as an industry standard. In addition, some high-power power supplies will also be equipped with passive (passive) or active (active) power factor correction (PFC) technology, which has become an industry standard. Passive power factor correction is usually implemented by using an inductor-capacitor compensation circuit or a valley-filling circuit, and the power factor can usually reach 0.7 to 0.9; while active power factor correction is more complicated but can achieve a high power factor of up to 0.99. In order to control the heat generation of the power supply, there is also a lower limit of the power conversion efficiency, such as the 80 PLUS specification certification for informal industry certification.At present, the input voltage of the commonly used ATX specification PC power supply is generally between 100V and 250V. The latest ATX specification is ATX version 2.31 released in mid-2008. Common storage controllers have adapters, such as sound cards and graphics cards. Adapter (Interface Card, Adapter) is the communication bridge between computer and peripheral hardware, for example: screen, keyboard, CD-ROM, printer, hard disk, etc., each of which can only work by transmitting data through the adapter. Most computers now have built-in adapters, and external adapters are added if necessary.A sound card is an interface card used to process sound in a multimedia computer. The sound card can convert the voice, music and other sounds from microphones, radios, recorders, CD players (laser discs) and other equipment into digital signals for processing by the computer, and save them in the form of files, and can also restore the digital signals to real sound output. . The interface at the rear of the sound card protrudes from the back of the chassis, and there are interfaces for connecting microphones, speakers, joysticks and MIDI devices.Graphics card (Video card, Display card, Graphics card, Video adapter) is one of the most basic components of a personal computer. It is used to convert the display information required by the computer system to drive the display and provide progressive or interlaced signals to the display. , which controls the correct display of the monitor, is an important component connecting the monitor and the motherboard of the personal computer, and is one of the important devices for "man-machine dialogueKey FeaturesBrandName：HRUIYL Package：Yes CoolingFin：No MemoryFrequency：2400MHz RGB：No Origin：CN(Origin) ModelNumber：DDR3DDR4 Type：DDR4 Application：Laptop ThevalueofCL：15 Sequence：7-7-7-20 InterfaceType：260Pin MemoryVoltage：1.2VV Frequency：1066mhz1333mhz1600mhz2133mhz2400mhz2666mhzMHzWhat's In the Box1*product
