Color that breathes.
6×12 RGB matrix with the AW20216S constant-current driver: gradients and effects without flicker.
In detail
LMX2 is a 6×12 RGB matrix driven by the AW20216S over SPI. Unlike a plain addressable panel, the AW20216S runs each LED at constant current, so you get clean gradients, smooth dimming and zero on-camera flicker. At 6 pixels wide, text is barely legible: this panel shines at pixel art, effects and ambient light. And it shares the same WuaDisplay-LMX library as LMX1, so you switch panels with a single build flag.

- Makers who want a quality SPI-driven RGB panel.
When addressable LEDs aren't enough
- Cheap WS2812 LEDs flicker on camera and dim with visible steps.
- Smooth gradients look banded and animation jitters.
- There's no panel made for art, not just text.
The LMX2 solution
- AW20216S constant-current driver: each of the 72 LEDs with stable brightness and fine dimming.
- SPI interface with an RGB565→RGB adapter for high refresh and fluid animation.
- A 6×12 vertical format built for pixel art, effects and ambient light.
What makes it special
Smooth brightness, no flicker
The AW20216S driver runs each LED at constant current: clean gradients and fine dimming, perfect for art and ambient lighting.
SPI control
A fast SPI interface and an RGB565→RGB adapter: high refresh for fluid animation.
Same API as LMX1
WuaDisplay-LMX treats LMX2 as just another panel: switch backend with a build flag, no project rewrite.
