Questions

How big is the Pid PCB?

It measures 108.5 × 107.7 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Pid use?

428 parts, built around the MAX44251AUA+, LM7171BIN, LMH6505MA and AD8421ARZ. 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 Pid KiCad files?

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

Can I use the Pid design in my own project?

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