WS2812B Description
WS2812B is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 ponents. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent.
