The 25 most common of 27 parts.
It measures 58.4 × 44.4 mm and has 2 copper layers, 1.6 mm thick.
27 parts, built around the ESP32-WROOM-32 and TSR 1-2433. 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 harry48225/twilight repository on GitHub, at the commit this page was made from: the board is pcb/pcb/pcb.kicad_pcb and its schematic pcb/pcb/pcb.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 harry48225 before reusing the design.
