Questions

What parts does the SWC nano use?

3 parts, built around the R-785.0-0.5. 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 SWC nano KiCad files?

From the kcorbett95/Steering-Wheel-Control-Adapter repository on GitHub, at the commit this page was made from: the board is SWC nano/SWC nano.kicad_pcb and its schematic SWC nano/SWC nano.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SWC nano design in my own project?

Its repository states no licence, so its author keeps all rights: ask kcorbett95 before reusing the design.
