Questions
How big is the Cereal PCB?
It measures 27 × 8.8 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Cereal use?
17 parts, built around the CP2102N-A01-GQFN20R and SP0503BAHTG. 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 Cereal KiCad files?
From the dotcypress/cereal repository on GitHub, at the commit this page was made from: the board is cereal.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cereal design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
