Questions
How big is the Midievol PCB?
It measures 190.5 × 127 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Midievol use?
57 parts, built around the 23LC1024-E/P, 24FC1026-I/SM and PC900V. 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 Midievol KiCad files?
From the ToeKnee/midievol repository on GitHub, at the commit this page was made from: the board is hardware/MIDIEvol/MIDIEvol.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Midievol 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).
