This repository is home to the MicroPython firmware and examples for Galactic, Cosmic and Stellar Unicorn - our Pico-powered LED matrix boards.
There are two choices, a regular build that just updates the firmware on your board and a "-with-examples" build which includes a ready-to-go set of examples (everything in examples/launcher) that you can interact with right on your display.
You can find the latest release at https://github.com/pimoroni/unicorn/releases/latest.
