Questions

How big is the PowerSupply PCB?

It measures 51 × 76 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PowerSupply use?

23 parts, built around the L7805 and L7809. 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 mradolovic/callisto repository on GitHub, at the commit this page was made from: the board is Hardware/Old boards/9V_5V_Power_Supply/PowerSupply.kicad_pcb and its schematic Hardware/Old boards/9V_5V_Power_Supply/PowerSupply.kicad_sch. 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 mradolovic before reusing the design.
