It measures 45 × 30 mm and has 2 copper layers, 1.61 mm thick.
40 parts, built around the ESP32-S3-WROOM-1-N8, MS5611-01BA03, AP2112K-3.3 and MPU-6050. 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 marstmu/flight-computer-f25 repository on GitHub, at the commit this page was made from: the board is kicad/F25.kicad_pcb and its schematic kicad/F25.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 marstmu before reusing the design.
