UCS9812 Pixel Protocol
A high-speed, two-wire (data and clock), individually addressable RGB LED protocol with a built-in IC for precise color and brightness control.
Overview
UCS9812 runs at 5V, supports 8-bit color and 5-bit global brightness, and is similar to APA102. It enables fast refresh rates, smooth animations, and long chains with minimal timing issues, ideal for complex displays and visual effects.
