Questions
What parts does the Front use?
189 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 Front KiCad files?
From the ayukmr/pendant repository on GitHub, at the commit this page was made from: the board is pcb/front/front.kicad_pcb and its schematic pcb/back/back.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Front 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).
