Questions
How big is the Mini C3 PCB?
It measures 84.1 × 23.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mini C3 use?
30 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 Mini C3 KiCad files?
From the JRegi/Mini-C3 repository on GitHub, at the commit this page was made from: the board is Mini-C3/Mini-C3.kicad_pcb and its schematic Mini-C3/Mini-C3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini C3 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).
