True color RGB LED HAT for Raspberry Pi, colorful display

Description

WS2812B is an intelligent LED controller of which the control circuit and the RGB chip are integrated in a package of 5050 components. It internally includes an intelligent digital port, a data latch and a signal reshaping amplification drive circuit. To ensure the color brightness consistent of the pixel light, it also contains a precision internal oscillator and a 12V voltage programmable constant current control part.

Its data transfer protocol uses single NZR communication mode. After the pixel is power-on and reset, the DIN port receives the data from the controller. The first 24 bit data is collected by the first pixel, and then sent to the internal data latch. The other data are reshaped by the internal signal reshaping amplification circuit and sent to the next cascade pixel through the DO port. After the transmission for all pixels, the signal may reduce to 24bit. The pixel adopts auto reshaping transmit technology, which allows the pixel cascade number is up to the speed of the signal transmission but not bound by the signal transmission restriction. For more information about auto reshaping transmit technology, please refer to the section data transfer protocol.
