FM Transmitter 1W High Power Transmitter Circuit Board Radio Broadcast Wireless Microphone Module PCB Amplifier C Type
FM Transmitter 1W High Power Transmitter Circuit Board Radio Broadcast Wirele Microphone Module PCB Amplifier C Type Operating Voltage: DC 2V- 9V Current: 9mA (3V voltage Reference distance: open ground 100 meters, 10-30 meters indoor envmental obstacles (3v voltage test, increasing the voltage from the greatly increased) Operating frequency: 85MHZ --- 115MHZ (usually between 99-101 boot default frequency) Receive way: as long as the 88-108MHz FM radio can receive, with FM feature phones. Frequency adjustment: adjustable capacitor Output Impedance: 50s Size:2 cm * 1cm L*W Aembly requirements: 1. Aemble this product. At least you should have a soldering and a multimeter to understand the basics of radio. 2, the module is debued, welding three wires (2 power supply 1 ) can be used. 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.
