Questions
What parts does the EL87 use?
272 parts, built around the AT90USB1286-MU. 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 EL87 KiCad files?
From the BalzGuenat/mechkeys repository on GitHub, at the commit this page was made from: the board is EL87/EL87.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EL87 design in my own project?
Its repository states no licence, so its author keeps all rights: ask BalzGuenat before reusing the design.
