It measures 107 × 64 mm and has 2 copper layers, 1.6 mm thick.
123 parts, built around the BME280, TPS63802DLAR, DW01A and TP4056-42-ESOP8. 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 VoiD7965/Station_Meteo_pcb repository on GitHub, at the commit this page was made from: the board is Station_Meteo_pcb.kicad_pcb and its schematic Alimentation.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 VoiD7965 before reusing the design.
