It measures 42 × 52 mm and has 2 copper layers, 1.6 mm thick.
105 parts, built around the TPP60308-ES1R-S, LS56 and SMCJ54CA. 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 baden/dropla-dc repository on GitHub, at the commit this page was made from: the board is board/dropla-dc/dropla-dc.kicad_pcb and its schematic board/dropla-dc/dropla-dc.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 baden before reusing the design.
