Questions
How big is the Watch PCB?
It measures 63.4 × 41.4 mm and has 8 copper layers, 1.6 mm thick.
What parts does the Watch use?
112 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 Watch KiCad files?
From the Mee42/watch repository on GitHub, at the commit this page was made from: the board is pcb/watch/watch.kicad_pcb and its schematic pcb/watch/watch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Watch design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mee42 before reusing the design.
