It measures 86.5 × 32.5 mm and has 2 copper layers, 1.6 mm thick.
38 parts, built around the MAX485ED. 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 kildom/home-controller repository on GitHub, at the commit this page was made from: the board is comm-board/comm-board.kicad_pcb and its schematic comm-board-ext-gw/comm-board-ext-gw.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 kildom before reusing the design.
