It measures 135.3 × 80 mm and has 4 copper layers, 4.69 mm thick.
49 parts, built around the L7805, TIP120 and WS2812B. 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 swindonmakers/new-thing-controller repository on GitHub, at the commit this page was made from: the board is new-thing-ctrl-hardware/new-thing-ctrl-hardware.kicad_pcb and its schematic new-thing-ctrl-hardware/new-thing-ctrl-hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
