Color that breathes, in a low profile.
The LMX2's 6×12 RGB matrix with the AW20216S driver, in an SMD version: the same flicker-free effects, more compact.
In detail
LMX2s is the SMD version of our 6×12 RGB matrix: the same panel driven by the AW20216S over SPI as the LMX2, but with surface-mount pads on the back instead of THT headers. You get the same clean gradients, smooth dimming and zero on-camera flicker, in a more compact (13.8 × 40 mm), low-profile format ideal for mounting flush against a surface. It shares the same WuaDisplay-LMX library as the rest of the family, so you switch panels with a single build flag.

Pinout
What each pin on the board maps to.
SMD pads on the back side, in a single row (left → right).
- V+ Power (5 V)
- CK SCK / Clock (SPI)
- MISO MISO (SPI)
- SK SYNC
- CS Chip Select (SPI)
- MOSI MOSI (SPI)
- EN Enable
- G GND (ground)
- Pixel-art artists and ambient-lighting designers.
- Effects projects, lamps and generative art.
- Makers and integrators who need surface-mount, low-profile boards.
When addressable LEDs aren't enough
- Cheap WS2812 LEDs flicker on camera and dim with visible steps.
- Smooth gradients look banded and animation jitters.
- Sometimes THT headers get in the way: you want something that sits flush.
The LMX2s 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.
- SMD pads on the back side: the same 6×12 panel, more compact (13.8 × 40 mm) and low-profile.
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.
SMD mounting, low profile
The same 6×12 panel as the LMX2 but with SMD pads on the back: more compact (13.8 × 40 mm) and ready to sit flush against a surface.
Same API as LMX1
WuaDisplay-LMX treats LMX2s as just another panel: switch backend with a build flag, no project rewrite.
