It measures 25.9 × 51.3 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the X161032768KJD2SI and X322524MSB4SI. 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 ZegesMenden/stm32-devboard repository on GitHub, at the commit this page was made from: the board is stm32-devboard.kicad_pcb and its schematic stm32-devboard.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 ZegesMenden before reusing the design.
