SK9822 Pixel Protocol
A high-speed, clocked, individually addressable RGB LED protocol with integrated IC, offering 8-bit color and 5-bit global brightness control for precise, smooth effects.
Overview
SK9822 uses a two-wire (data and clock) SPI-like interface, operates at 5V, and is similar to APA102, supporting fast refresh rates, smooth gradients, and long chains with minimal timing issues.
