Questions
How big is the Matrix PCB?
It measures 53 × 41.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Matrix use?
73 parts, built around the ESP32-C6-MINI-1U-H4. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Matrix KiCad files?
From the ayukmr/matrix repository on GitHub, at the commit this page was made from: the board is pcb/matrix.kicad_pcb and its schematic pcb/matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Matrix design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
