WS2811 Pixel Protocol
A single-wire, individually addressable RGB LED protocol with an external IC for robust 24-bit color control.
Overview
WS2811 typically operates at 12V and controls three LEDs per IC as a group. Its higher voltage allows for longer runs with reduced voltage drop, making it popular for large-scale installations and outdoor displays.
