1pc 24‑Bit WS2812 5050 RGB LED Ring Lamp Light With

Features:Round and round and round they go! 24 ultra bright smart LED are arranged in a circle with 3.3"(85mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one micro-controller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time micro-controller such as an AVR, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted micro-controller. Our wonderfully-written library supports these pixels! As it requires hand-tuned embly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.

4-20mA Generator Adjustable Analog Quantity Current Signal

Features:Input power is DC 3.3-30V, recommended power supply is 12-24VDC.Input power supply, product can generate 4-20mA current output by manual adjusting potentiometer, used for current analog quantity 4-20mA output.Output current can be constant automatically at setting value according to adjustment; it can also be used as a constant current source of which the maximum output current should not exceed 20mA.Universal power supply of module, can be used for PLC, frequency converter, servo.Module power consumption current is less than 30mA, supports for general equipment.Specifications:Type: Current generatorModel: 4-20mAPotentiometer Installation Hold Diameter: 10mmSize(L*W*H): 73*54*30mm/2.9*2.1*1.2inHole Spacing: 61mm/2.4in Suitable Screws: M3 (NOT included)Weight: 74g(approx.)Wiring:3-32V: DC power supply positiveGND(left): Power supply negative GND(right): 4-20mA output current negative4-20mA-OUT: 4-20mA output current positivePotentiometer: Adjust output range of 4-20mA, clockwise to increase, counterclockwise to reduceInstruction:About Output Impedance Matching:Output signal resistance must meet the following requirementsAccording to the formula:I=U/R(current = voltage/resistance)So the maximum current that signal receiving end can generate is equal to dividing power supply voltage by signal resistance.In this way, current generator still has some resistance.Thus concludes to a formula:Power supply voltage/(signal internal resistance + current generator internal resistance) = output constant currentOur module power supply is 5-32V voltage, so if using low voltage power supply, and the signal internal resistance is large, the output constant current will not be enough.Signal matching requirements is given below:For 24V power supply, signal resistance shall not be greater than 1000 ohms.For 12V power supply, signal resistance shall not be greater than 500 ohms.For 5V power supply, signal resistance shall not be greater than 200 ohms.If your signal resistance is greater than the above parameters, you can improve the power supply voltage or reduce internal resistance, to ensure a enough constant current source.Note that the power supply voltage cannot be more than 32V.This module can be used for PLC, frequency converter, servo; and when using these products, the module's voltage should match your interface. If you are not sure, you can try 5V first, then 12V or 24V power supply. Under the condition of normal function, use low voltage as far as possible.There is another way:In general, PLC, frequency converter, or server has a COM +, COM - power output interface, power supply can be directly from here.Package Includes:1 x Signal GeneratorKey FeaturesInput power is DC 3.3-30V, recommended power supply is 12-24VDC.Input power supply, product can generate 4-20mA current output by manual adjusting potentiometer, used for current analog quantity 4-20mA output.Output current can be constant automatically at setting value according to adjustment; it can also be used as a constant current source of which the maximum output current should not exceed 20mA.Universal power supply of module, can be used for PLC, frequency converter, servo.Module power consumption current is less than 30mA, supports for general equipment.What's In the Box1 x Signal Generator

1pc 16‑Bit I2C ADC Development Board Analog To Digital

Features:For micro-controllers without an analog-to-digital converter or when you want a higher-precision ADC, provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter. The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the data-sheet table 5) so you can have up to 4 connected on a single 2-wire I2C bus for 16 single ended inputs.Four single-ended or two differentialinputs. Programmable comparator; internal low-driftvoltage reference; internal oscillator; internal PGA.This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers.Specifications:Wide Supply Range: 2.0v to 5.5v;Low Current Consumption: Continuous Mode:Only 150uA Single-Shot Mode: Auto Shut-Down;Programmable Data Rate: 8sps to 860sps;I2C Interface: Pin-selectable addresses;Size:2.8*1.8cm/1.1*0.7inWeight: 5g(approx.)Package Includes:1 x Module1 x Pin HeaderDear customer, thank you very much for choosing my store.
