Questions

How big is the Test op PCB?

It measures 79.5 × 38.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Test op use?

47 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 Test op KiCad files?

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

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

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