This is the start of a series of mods that you'll be able to hand wire to your builds, whether they be keyboards, Arduinos or Raspberry Pis. They're meant for adventurous tinkerers, and may be a challenge to fit into your builds. If that's up your alley, do check out these components!

A tiny, tightly-packed matrix of 77 individually-controllable bright white LEDs. Ideal for scrolling text, animations, bar graphs, or just general illumination, and it's Raspberry Pi and Arduino-compatible.

This tiny, white LED matrix has 77 pixels packed onto a board that's the same size as a postage stamp! Each LED's brightness can be controlled individually, meaning that you can display all sorts of cool text, animations, and more on it.

These modules require custom code to run, which means you need to be familiar with QMK to add it to your keyboard. Over time, sample code will become available, but at the moment it is not. If you'd like a solution that's ready out of the box, I recommend not purchasing this addon, as support will be limited.
