Questions
How big is the Circuits PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Circuits use?
19 parts, built around the MCP2515-I/P and CSTLS20M0X51-B0. 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 Circuits KiCad files?
From the mocketech/EmoGo repository on GitHub, at the commit this page was made from: the board is board/circuits/board/board.kicad_pcb and its schematic board/circuits/board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Circuits 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).
