Questions

How big is the Peru satu current PCB?

It measures 21.8 × 29.4 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Peru satu current use?

22 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 Peru satu current KiCad files?

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

Can I use the Peru satu current design in my own project?

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