Questions
What parts does the Auto discharge use?
9 parts, built around the SD560B. 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 Auto discharge KiCad files?
From the matterwaves/auto-discharge repository on GitHub, at the commit this page was made from: the board is auto-discharge.kicad_pcb and its schematic auto-discharge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Auto discharge design in my own project?
Its repository states no licence, so its author keeps all rights: ask matterwaves before reusing the design.
