Questions
How big is the Pro micro c PCB?
It measures 36.8 × 17.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pro micro c use?
26 parts, built around the ATMEGA32U4-MU and MIC5219-3.3YM5. 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 Pro micro c KiCad files?
From the sowbug/pro-micro-c repository on GitHub, at the commit this page was made from: the board is pro-micro-c.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pro micro c design in my own project?
Its repository states no licence, so its author keeps all rights: ask sowbug before reusing the design.
