Features: 1. Smart reverse protection, power back-up does not damage the IC. 2. IC control circuit and LED point light use one common power supply. 3. The control circuit is integrated with the RGB chip in a 5050-package component to form a complete external control pixel. 4. Built-in signal shaping circuit, any one pixel point received signal after the waveform shaping and then output which ensure that the line waveform distortion will not accumulate. 5. Built-in power-on reset and power-down reset circuit. 6. Each pixel of the three primary colors to achieve a 256-level brightness display, complete 16777216 colors of the full true color display, scanning frequency is not less than 400hz/s. 7. Serial-level connection port, it can receive and decode data through a signal line. 8. The distance of any two-point transmission which is no more than 5 meters do not need any electrical circuit. 9. Data transmission can speed up to 800Kbps. 10. Light color is highly consistent and cost-effective Specification: Condition: 100% Brand New Model: WS2812B Color: RGB Weight: Approx. 5g / 0.2oz Package List: 1 * LED Development Board 1、Smart reverse protection, power back-up does not damage the IC. 2、IC control circuit and LED point light use one common power supply. 3、The control circuit is integrated with the RGB chip in a 5050-package component to form a complete external control pixel. 4、Built-in signal shaping circuit, any one pixel point received signal after the waveform shaping and then output which ensure that the line waveform distortion will not accumulate. 5、Built-in power-on reset and power-down reset circuit.
