Questions
How big is the DCDCTypeC PCB?
It measures 24 × 36 mm and has 2 copper layers, 0.8 mm thick.
What parts does the DCDCTypeC use?
25 parts, built around the CH224K, MCP16301-E/CH, B260S1F and CUS08F30. 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 DCDCTypeC KiCad files?
From the medo64/Electronics.Test.DcDcTypeC repository on GitHub, at the commit this page was made from: the board is src/DCDCTypeC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCDCTypeC 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).
