Questions
What parts does the Cube use?
30 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 Cube KiCad files?
From the akkdong/Cube repository on GitHub, at the commit this page was made from: the board is M3/hw/M3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cube design in my own project?
Its repository states no licence, so its author keeps all rights: ask akkdong before reusing the design.
