Questions
How big is the USB MidiController PCB?
It measures 119.4 × 88.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB MidiController use?
31 parts, built around the ATMEGA32-16PU and 74LS573PC. 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 USB MidiController KiCad files?
From the derrudi187/USB-MidiController repository on GitHub, at the commit this page was made from: the board is schematic/USB-MidiController.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB MidiController 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).
