WS2818 is the upgrade of ws2811, but has one more data back up, or we can say it is ws2813/ws2815 IC put in a DFN8 package.
WS2818 Wiring Diagram
WS2818 is a 3-channel LED driver control circuit that includes an intelligent digital port data latch and a signal reshaping amplification drive circuit.
It also includes a precision internal oscillator and a programmable 12V voltage constant current control component, which achieves a highly consistent color effect.
WS2818 adopts dual signal transmission so that these signals can operate together without interference.
But if one signal is interrupted for some cause, the other signal persists, and any single pixel failure has no effect on the other pixels, no over-display effect, no waveform distortion.
