Questions
How big is the Midiguitarpcb PCB?
It measures 70 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Midiguitarpcb use?
49 parts, built around the AMS1117-3.3, DIN-504D-M5 and NMJ6HCD2. 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 Midiguitarpcb KiCad files?
From the grasevski/midiguitar repository on GitHub, at the commit this page was made from: the board is schematic/midiguitarpcb.kicad_pcb and its schematic schematic/midiguitarpcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Midiguitarpcb design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
