Questions
How big is the Keyboard layout PCB?
It measures 139.4 × 101.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard layout use?
77 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 Keyboard layout KiCad files?
From the Jrezky/MK-pcb-tutorial repository on GitHub, at the commit this page was made from: the board is keyboard-layout-pcb/keyboard-layout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard layout design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
