It measures 63.2 × 38.5 mm and has 2 copper layers, 1.6 mm thick.
25 parts, built around the ESP32-WROOM-32D, DS18B20 and LM1117MPX-33NOPB. 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 vmangelschots/hades-poolcontroller-pcb repository on GitHub, at the commit this page was made from: the board is hades.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 vmangelschots before reusing the design.
