Questions
How big is the Motherboard PCB?
It measures 73.7 × 76.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Motherboard use?
92 parts, built around the ADP2302ARDZ-5.0-R7, ADP2303ARDZ-3.3-R7, MCP9804-E/MC and DM3AT-SF-PEJM5. 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 bfrigon/alarm-clock-hardware repository on GitHub, at the commit this page was made from: the board is pcb/motherboard/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 publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
