It measures 49.6 × 49.6 mm and has 2 copper layers, 1.6 mm thick.
34 parts, built around the PCA9557D. 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 ciniml/M5Stack_WiSUN repository on GitHub, at the commit this page was made from: the board is M5Stack_WiSUN.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 ciniml before reusing the design.
