It measures 127 × 127 mm and has 2 copper layers, 1.6 mm thick.
70 parts, built around the LM358N, LM311N, LM7812 and IRF740. 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 xunil/hvsupply repository on GitHub, at the commit this page was made from: the board is hvsupply.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 xunil before reusing the design.
