Questions
How big is the Mechkey PCB?
It measures 62.8 × 38 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mechkey use?
24 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 Mechkey KiCad files?
From the sle-c/mechkey repository on GitHub, at the commit this page was made from: the board is mechkey.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mechkey design in my own project?
Its repository states no licence, so its author keeps all rights: ask sle-c before reusing the design.
