It measures 20.4 × 28.5 mm and has 4 copper layers, 1.6 mm thick.
22 parts, built around the TLV75733PDBVR-MS. 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 engstad/STM32F042-Mini repository on GitHub, at the commit this page was made from: the board is STM32F042-Mini.kicad_pcb and its schematic STM32F042-Mini.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 engstad before reusing the design.
