Questions
How big is the Mochi40 PCB?
It measures 265.1 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mochi40 use?
121 parts. 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 Mochi40 KiCad files?
From the Aidan-OS/Mochi40 repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/Hotswap Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mochi40 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).
