Questions
How big is the Midi project PCB?
It measures 95 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Midi project use?
29 parts, built around the ATMEGA32U4-AU. 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 Midi project KiCad files?
From the cester-ino/Midi_project repository on GitHub, at the commit this page was made from: the board is main_board/main_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Midi project 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).
