The 84 most common of 88 parts.
It measures 146.1 × 125.2 mm and has 6 copper layers, 1.6 mm thick.
88 parts, built around the IRS21867S. 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 supermileage/UrbanMotorControllerPCB repository on GitHub, at the commit this page was made from: the board is Urban MC.kicad_pcb and its schematic Urban MC.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 supermileage before reusing the design.
