It measures 180.1 × 180.3 mm and has 2 copper layers, 1.6 mm thick.
237 parts, built around the ATTINY13A-SU, ESD7951ST5G, MBRS540T3 and BC301N-D. 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 LibreRouterOrg/board repository on GitHub, at the commit this page was made from: the board is designs/mega_board/LibreRouter_MegaBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
