It measures 83.1 × 66.5 mm and has 2 copper layers, 1.6 mm thick.
17 parts, built around the E73-2G4M08S1C. 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 fduignan/nrf52833 repository on GitHub, at the commit this page was made from: the board is DublinMaker2022/KiCAD_PCB/dmb2022/dmb2022.kicad_pcb. 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).
