It measures 110.2 × 79.8 mm and has 2 copper layers, 1.6 mm thick.
172 parts, built around the DS3231MZ+. 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 Danielfgb/RPi-Protector-Extensor-GPIO repository on GitHub, at the commit this page was made from: the board is Module_RPI.kicad_pcb and its schematic Estado_GPIO.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 Danielfgb before reusing the design.
