Questions
What parts does the Choc use?
31 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 Choc KiCad files?
From the aditya23043/split28 repository on GitHub, at the commit this page was made from: the board is case/choc/choc.kicad_pcb and its schematic case/choc/choc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Choc design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
