It measures 65 × 70 mm and has 2 copper layers, 1.6 mm thick.
88 parts, built around the MPM3610AGQV-P, BME690, CH224K and ESP32-C5-MINI-1. 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 Sankie005/CAIR repository on GitHub, at the commit this page was made from: the board is Charan_Indoor.kicad_pcb and its schematic Charan_Indoor.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 Sankie005 before reusing the design.
