Questions
How big is the Watch wrong PCB?
It measures 15.2 × 8.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Watch wrong use?
35 parts, built around the ATMEGA328-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 Watch wrong KiCad files?
From the sulkith/BCDWristWatch repository on GitHub, at the commit this page was made from: the board is Schematics/Schematics_328P/Watch_wrong.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Watch wrong 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).
