WS2812B is addressable and programmable LED, means, user can make a chain of multiple WS2812B module and control individually. As the module is very small not even 1 CM can be used anywhere in the project. It is an intelligent light source that controls the circuit. The module has integrated RGB led chip in the package of 5050 components. The internal circuit includes an intelligent port data latch, signal reshaping amplification drive circuit, precision internal oscillator and a 12V voltage programmable constant current control part, which ensures pixel point light colour height consistent. 

WS2812B uses NZR communication mode as a data transfer protocol
