Questions
How big is the CMKC65 R1 PCB?
It measures 313.9 × 119.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CMKC65 R1 use?
141 parts, built around the 74HC4514D. 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 CMKC65 R1 KiCad files?
From the thomasdevine01/cmkc-keyboard repository on GitHub, at the commit this page was made from: the board is Kicad Files/-R1/CMKC65_R1.kicad_pcb and its schematic Kicad Files/-R1/CMKC65_R1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CMKC65 R1 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).
