“Learn how to use WS2812B RGB LED in custom circuits
so you have used Neopixel Rings/Strips/Matrix in one of your projects and now you want to make a circuit and add WS2812B LED on it but don’t know-how?
WS2812B is an intelligent control LED light source that the control circuit and RGB chip are integrated into a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit.
The data transfer protocol uses a single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the first pixel collects initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission.
well, read its datasheet for more info- datasheet
