Pimoroni Galactic Unicorn

The board as it appears on the Velxio canvas, with its full pin map read live from the simulator (regenerated by scripts/gen-boards.mjs, so it always matches what you can wire).

About this board

Pimoroni’s 53x11 RGB matrix — 583 individually addressable pixels — driven by a Pico 2 W (RP2350) on the back of the same board, with the A/B/C/D buttons and the volume and brightness pairs along the edge.

The matrix is the board: only six pins appear in the map below, because everything else is the panel and its driver. Projects here are about what you draw on 583 pixels, not about what you wire.

GPIO heartbeat is the board’s simplest sketch and the quickest confirmation that it runs.
