It measures 50.5 × 20 mm and has 2 copper layers, 1.09 mm thick.
18 parts, built around the S2B-PH-SM4-TB. 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 zshivers/PlayaNavigator repository on GitHub, at the commit this page was made from: the board is hardware/pcb/PlayaNavigatorHw.kicad_pcb and its schematic hardware/pcb/PlayaNavigatorHw.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
