Questions
How big is the ProtoCV PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ProtoCV use?
142 parts, built around the 74AHCT244D, R-78E3.3-0.5, OPA4192ID and BC847. 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 ProtoCV KiCad files?
From the marangisto/ProtoCV repository on GitHub, at the commit this page was made from: the board is ProtoCV.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProtoCV 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).
