Questions
What parts does the AnalogWatch use?
75 parts, built around the ATMEGA328P-MU. 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 AnalogWatch KiCad files?
From the sulkith/BCDWristWatch repository on GitHub, at the commit this page was made from: the board is Schematics/Schematics_analog_328P/AnalogWatch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AnalogWatch 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).
