Questions
How big is the PR-4PP PCB?
It measures 84.1 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PR-4PP use?
36 parts, built around the ATMEGA32U4-AU and SRV05-4. 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 PR-4PP KiCad files?
From the RodPaDev/PR-4PP repository on GitHub, at the commit this page was made from: the board is PR-4PP.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PR-4PP 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).
