The WS2812B is a new generation of the product based on WS2812. The pixel adopt an auto reshaping transmit technology, making the pixel cascade number is not limited the signal transmission only depend on the speed of the signal transmission. When powering the pixel the D-IN port receive data from the microcontroller, the first pixel collect initial a 24bit of data then sent to the internal data latch, the other data which is 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 will reduce to 24bit. The data transfer protocol uses a single NZR communication mode. It is an onboard intelligent digital port latch and signal reshaping implication drive circuit an effectively ensuring that the pixel point light color are HIGH and consistent. The WS2812 is a family of smart LED light source that control circuit and RGB chip are integrated in a package 50-50 component. There are two types or version of WS2812 the WS2812 and the WS2812B see the diagram below the difference between the two of theme. In this illustration we’re going to wire the 8bit WS2812B 50-50 which Chainable, addressable LED (Light Emitting Diode) A precise on any vivid colorful light mixing animation, these module as the example for this demonstration we going to control each WS2812B LED using Digital and serial communication.
