MY9221 Pixel Protocol
A clocked, constant-current LED driver protocol with 12 channels and 8-bit grayscale control, designed for precise and uniform RGB or multi-channel LED applications.
Overview
MY9221 uses a two-wire (data and clock) interface, supports 3.3V–5V operation, and is optimized for multi-channel color mixing and stable brightness across all LEDs.
