Questions
How big is the MidiKeyboard PCB?
It measures 167.5 × 82 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MidiKeyboard use?
11 parts, built around the SK6812MINI-E. 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 MidiKeyboard KiCad files?
From the CodingJamMan/MidiKeyboard repository on GitHub, at the commit this page was made from: the board is midi-keyboard.kicad_pcb and its schematic midi-keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MidiKeyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask CodingJamMan before reusing the design.
