It measures 80 × 45 mm and has 2 copper layers, 1.6 mm thick.
39 parts, built around the LM358, BC547, BC557 and IRF3205. 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 BOTwot/Dhere_pcb_mod_v1 repository on GitHub, at the commit this page was made from: the board is dhere_mod_1.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 BOTwot before reusing the design.
