Questions
How big is the Midi plus PCB?
It measures 176.8 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Midi plus use?
23 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 Midi plus KiCad files?
From the Stanlee1234/midi-plus repository on GitHub, at the commit this page was made from: the board is KiCad/KiCad.kicad_pcb and its schematic KiCad/KiCad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Midi plus design in my own project?
Its repository states no licence, so its author keeps all rights: ask Stanlee1234 before reusing the design.
