It measures 64 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
101 parts, built around the MPZ2012S102JTD25, SJ-43515TS, 2M1-SP1-T1-B1-M2QE and BC856. 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 GiesbrechtElectronics/GEQ1 repository on GitHub, at the commit this page was made from: the board is GEQ1_AusfB_R3/GEQ1_AusfB_R3.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).
