It measures 40.6 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
9 parts, built around the BME280. 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 tgobrien1/envmon-pcb repository on GitHub, at the commit this page was made from: the board is Atmospheresensor3.0/Atmoshpheresensor3.0.kicad_pcb and its schematic Atmospheresensor3.0/Atmoshpheresensor3.0.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 tgobrien1 before reusing the design.
