Questions
How big is the Bluepill USB C PCB?
It measures 20.7 × 51.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Bluepill USB C use?
44 parts, built around the W25Q32JVSSIQ, SPX3819M5-L-3-3 and BAT54C. 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 Bluepill USB C KiCad files?
From the rohamid/Bluepill-USB-C repository on GitHub, at the commit this page was made from: the board is Bluepill-USB-C.kicad_pcb and its schematic Bluepill-USB-C.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bluepill USB C design in my own project?
Its repository states no licence, so its author keeps all rights: ask rohamid before reusing the design.
