Questions
How big is the YAEMK PCB?
It measures 165.8 × 130.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the YAEMK use?
218 parts, built around the LMV321, SRV0504, CAT24C512WI- and XC6206P332MR. 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 YAEMK KiCad files?
From the KarlK90/yaemk-split-kb repository on GitHub, at the commit this page was made from: the board is PCB/YAEMK.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the YAEMK 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).
