It measures 23.5 × 14 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 ericjhoh/ME-433 repository on GitHub, at the commit this page was made from: the board is HW15/ME_433/ME_433.kicad_pcb and its schematic HW15/ME_433/ME_433.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 ericjhoh before reusing the design.
