Questions
How big is the Mill music PCB?
It measures 87.1 × 51.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mill music use?
55 parts, built around the ATMEGA328-AU and LM1117-5.0. 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 Mill music KiCad files?
From the jonronen/kicad-stuff repository on GitHub, at the commit this page was made from: the board is mill_music/mill_music.kicad_pcb and its schematic pseudo_reverb/pseudo_reverb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mill music design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonronen before reusing the design.
