It measures 110.2 × 55.4 mm and has 2 copper layers, 1.6 mm thick.
167 parts, built around the LMH6505MA and LM7171BIN. 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.
From the bec5-group/pid-controller repository on GitHub, at the commit this page was made from: the board is test-op2/test-op2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask bec5-group before reusing the design.
