Questions

How big is the Mini power PCB?

It measures 20.3 × 27.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Mini power use?

8 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 Mini power KiCad files?

From the philopon/mini-power repository on GitHub, at the commit this page was made from: the board is mini-power.kicad_pcb and its schematic mini-power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Mini power design in my own project?

Its repository states no licence, so its author keeps all rights: ask philopon before reusing the design.
