WS2813B is a intelligent control and signal motor drive integrated circuit with an improved side-feeding solution. It combines the features of WS2812B, including self-adhesive PWM and signal break-point continuous transmission and a improved signal line circuit, which ensures smoother color changing and realizable stepping effect. It also has a improved circuit structure which supports conversion from three wire (ground, 5V and data) to two wire (ground and data) and single-signal connection for cascading. With transmission clock speed over 800 KHz, updating every pixel can be done in 24 microseconds, allowing for creating more sophisticated light synchronization effects. Additionally, it includes an internal power off reset circuit, supporting power off and power on reset, and it is also ESD-protected.
