Questions
What parts does the EurorackPSU use?
25 parts, built around the LM7812 and LM7912T. 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 EurorackPSU KiCad files?
From the spmasterman/EurorackPSU repository on GitHub, at the commit this page was made from: the board is EurorackPSU.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EurorackPSU design in my own project?
Its repository states no licence, so its author keeps all rights: ask spmasterman before reusing the design.
