Questions
How big is the MusicController PCB?
It measures 70 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MusicController use?
10 parts. 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 MusicController KiCad files?
From the imhwinters/MusicController repository on GitHub, at the commit this page was made from: the board is PCB/Music Controller.kicad_pcb and its schematic PCB/Music Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MusicController design in my own project?
Its repository states no licence, so its author keeps all rights: ask imhwinters before reusing the design.
