OpenDIAG - Open Source OBD2 Interface (Hardware)
It measures 186.6 × 104 mm and has 6 copper layers, 1.6 mm thick.
160 parts, built around the FAN7842MX, LM2576HVS-5, 74HC4051 and LM393. 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 CraftsmanSJ/Bicopter-PCB repository on GitHub, at the commit this page was made from: the board is Eshwar.kicad_pcb and its schematic Eshwar.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask CraftsmanSJ before reusing the design.
