It measures 44 × 72 mm and has 2 copper layers, 1.6 mm thick.
47 parts, built around the STM32G070CBT6, TP4054-42-SOT25R, XC6206P332MR-G and CL21A106KAYNNNE. 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 mrkct/console repository on GitHub, at the commit this page was made from: the board is hardware/console.kicad_pcb and its schematic hardware/console.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 mrkct before reusing the design.
