Questions

How big is the XFaders keys PCB?

It measures 354.3 × 53.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the XFaders keys use?

88 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 XFaders keys KiCad files?

From the essigt/SpareFaders repository on GitHub, at the commit this page was made from: the board is Hardware/pcb/xFaders_keys/xFaders_keys.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the XFaders keys design in my own project?

Its repository states no licence, so its author keeps all rights: ask essigt before reusing the design.
