The 84 most common of 88 parts.
It measures 110 × 110 mm and has 2 copper layers, 1.6 mm thick.
88 parts, built around the LMV358, L7805, IRLML6401 and FCR7350R. 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 SPROJ1Group5/finalPCB repository on GitHub, at the commit this page was made from: the board is SPROJ1_G5_MultiM_V2.kicad_pcb and its schematic SPROJ1_G5_MultiM_V2.kicad_sch. 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).
