Questions

What parts does the DualSourceDC use?

19 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 DualSourceDC KiCad files?

From the dluque465/DualSource repository on GitHub, at the commit this page was made from: the board is dualSourceDC.kicad_pcb and its schematic dualSourceDC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DualSourceDC design in my own project?

Its repository states no licence, so its author keeps all rights: ask dluque465 before reusing the design.
