Questions

How big is the Physbryk power supply PCB?

It measures 50.8 × 72.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Physbryk power supply use?

12 parts. 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 Physbryk power supply KiCad files?

From the Geoffysicist/PhysBrykPy repository on GitHub, at the commit this page was made from: the board is docs/resources/physbryk_power_supply/physbryk_power_supply.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Physbryk power supply design in my own project?

Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
