Questions
What parts does the Motherboard use?
134 parts, built around the 74LVC125AD, MCP9600-E/MX, LMR23625CDDA and TPS565208DDC. 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 Motherboard KiCad files?
From the MuddJTS/Motherboard repository on GitHub, at the commit this page was made from: the board is motherboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motherboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask MuddJTS before reusing the design.
