It measures 68.9 × 53.6 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the ARDUINO UNO R3. 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 pepassaco/Shielduinoboy repository on GitHub, at the commit this page was made from: the board is KiCAD/Shielduinoboy.kicad_pcb and its schematic KiCAD/Shielduinoboy.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).
