Questions
What parts does the RedunDCv1 use?
71 parts, built around the BS170. 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 RedunDCv1 KiCad files?
From the spreadspace/redunDC repository on GitHub, at the commit this page was made from: the board is hardware/redunDCv1/redunDCv1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RedunDCv1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask spreadspace before reusing the design.
