It measures 58.4 × 32.4 mm and has 2 copper layers, 1.6 mm thick.
26 parts, built around the CH340C, ESP32-WROOM-32, AMS1117-3.3 and SS8050. 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 sumitraj7766/ESP32-PCB repository on GitHub, at the commit this page was made from: the board is KiCad/esp32.kicad_pcb and its schematic KiCad/esp32.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 sumitraj7766 before reusing the design.
