Questions
What parts does the Eurorack-1u output use?
39 parts, built around the NE5532, TL072, 1N4148WS and B140HW-7-HXY. 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 Eurorack-1u output KiCad files?
From the sampozki/1U-output-module repository on GitHub, at the commit this page was made from: the board is eurorack-1u-output.kicad_pcb and its schematic eurorack-1u-output.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eurorack-1u output design in my own project?
Its repository states no licence, so its author keeps all rights: ask sampozki before reusing the design.
