Questions
How big is the Keychaingame PCB?
It measures 5.1 × 12.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keychaingame use?
28 parts, built around the ATTINY13A-MMF, MIC5205-2.5BM5 and SN74HC595DRG3. 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 Keychaingame KiCad files?
From the pollend/keychaingame repository on GitHub, at the commit this page was made from: the board is keychain_game.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keychaingame design in my own project?
Its repository states no licence, so its author keeps all rights: ask pollend before reusing the design.
