Questions
How big is the Keychains PCB?
It measures 81.4 × 78.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keychains use?
22 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 Keychains KiCad files?
From the surac10/Projects repository on GitHub, at the commit this page was made from: the board is electrical_projects/star_keychain_pcb/pcb/Keychains.kicad_pcb and its schematic electrical_projects/boost_converter/schematic/BoostConverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keychains design in my own project?
Its repository states no licence, so its author keeps all rights: ask surac10 before reusing the design.
