Questions

How big is the Test power PCB?

It measures 146.8 × 36.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Test power use?

72 parts, built around the L7812, SG3525A, ES2D and IRF530N-VB. 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 Test power KiCad files?

From the bec5-group/pid-controller repository on GitHub, at the commit this page was made from: the board is test-power/test-power.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

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

Its repository states no licence, so its author keeps all rights: ask bec5-group before reusing the design.
