It measures 48 × 48 mm and has 2 copper layers, 1.6 mm thick.
12 parts, built around the LM358, PPTC041LFBN-RC and IRFZ44N. 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 agusff/Proyecto-Miliohmetro repository on GitHub, at the commit this page was made from: the board is Miliohmetro_V1.0/Miliohmetro_V1.0.kicad_pcb and its schematic Miliohmetro_V1.0/Miliohmetro_V1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask agusff before reusing the design.
