It measures 129.5 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
31 parts, built around the ATMEGA168A-PU, V7805-1000 and KS-01Q-01. 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 NSagan271/HOPE-Project repository on GitHub, at the commit this page was made from: the board is HOPE_Project.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask NSagan271 before reusing the design.
