LED WS2811 WS2812 component
A simple chained RGB LED controller IC allowing multiple LEDs to be controlled using a serial data stream. Compatible with the WS2811, WS2812 and WS2812B Type Controller ICs. Allows RGB LEDs to be driven with full 24-bit colour depth. Allows single chains, 2D arrays and 3D cube formations to be simulated. Requires a high speed microcontroller to generate the critical timings to drive the device.
