WS2818B Overview
WS2818B Single-line 256 Gray-level 3-channel Constant Current LED Driver.
WS2818B Key Features
- 12V application
- Built-in VR-tube, only add a resistance to IC VDD-pin if under 12V, no external VR-tube needed
- Adopts the built-in signal reshaping circuit to achieve the signal waveform shaping, and thus no signal waveform
- Built-in power-on reset and brown-out reset circuits
- The gray levels of each pixel of 256 levels, and the refresh frequency reaches to 2KHz
- Serial cascading interface, data receiving and decoding are all achieved by one signal line
- Signal Break-point Continuous Transmission, any pixel’s failure, it won’t affect the whole display effect
- The distance of any two signal transmission points is less than 5 meters, there’s no extra circuits needed
- When the refresh rate of 30fps, the cascade number are not less than 1024 pixels
- Send data at speeds of 800Kbps
