The WS2811 and WS2812 are types of intelligent control LED light source that are based on a single-wire control protocol. They are often used to create colorful lighting effects in devices such as LED strips, holiday decorations, and stage lighting. The WS2811 is a 3-channel LED driver with an internal processor that allows it to receive data over a single wire, while the WS2812 is a newer version with a built-in LED that integrates the driver into the LED itself. Both types of module can be controlled using a microcontroller or other device that sends data over a single wire to the module. This data is used to set the color and brightness of the LED.

This is a breakout board for the built in WS2812 RGB LED. The WS2812 is actually an RGB LED with a WS2811 built right into the LED! All the necessary pins are broken out to 0.1" spaced headers for easy bread-boarding. Several of these breakouts can be chained together to form a display or an addressable string.This is a breakout board for the built in WS2812 RGB LED.
