Questions
How big is the Example PCB?
It measures 62 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Example use?
30 parts, built around the ATMEGA32U4. 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 Example KiCad files?
From the JJKeyboards/example repository on GitHub, at the commit this page was made from: the board is example.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Example 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).
