It measures 67.3 × 99.7 mm and has 2 copper layers, 1.6 mm thick.
40 parts, built around the ESP32-WROOM-32D, CH340G, LM2596S-5.0 and AMS1117-3.3. 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 oakayasaroglu/esp32d_i2c repository on GitHub, at the commit this page was made from: the board is sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask oakayasaroglu before reusing the design.
