Questions
What parts does the Powersupply use?
12 parts, built around the L7815 and L7915. 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 Powersupply KiCad files?
From the sonic2000gr/schoolspace repository on GitHub, at the commit this page was made from: the board is Schematics/PowerSupply/powersupply/powersupply.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Powersupply design in my own project?
Its repository states no licence, so its author keeps all rights: ask sonic2000gr before reusing the design.
