The 90 most common of 92 parts.
It measures 83 × 53.5 mm and has 4 copper layers, 1.6 mm thick.
92 parts, built around the ESP32-C3-WROOM-02-H4, BME280, MAX4466EXK+T and W25Q32JVSSIQ. 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 BBIkal/ESP32_IOT_Project repository on GitHub, at the commit this page was made from: the board is ESP 32 PCB Project.kicad_pcb and its schematic ESP 32 PCB Project.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 BBIkal before reusing the design.
