Questions
How big is the Button board PCB?
It measures 131 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Button board use?
27 parts, built around the CD74HC4067M. 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 Button board KiCad files?
From the cester-ino/Midi_project repository on GitHub, at the commit this page was made from: the board is button_board/button_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Button board 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).
