It measures 150.5 × 91.5 mm and has 2 copper layers, 1.6 mm thick.
11 parts. 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 RAGULN23/pcb_es repository on GitHub, at the commit this page was made from: the board is ragul.kicad_pcb and its schematic iot.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 RAGULN23 before reusing the design.
