Questions
How big is the Proto PCB?
It measures 76.2 × 50.8 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Proto use?
307 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 Proto KiCad files?
From the STM32World/hardware repository on GitHub, at the commit this page was made from: the board is proto/proto.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Proto design in my own project?
Its repository states no licence, so its author keeps all rights: ask STM32World before reusing the design.
