It measures 15 × 30 mm and has 2 copper layers, 1.6 mm thick.
35 parts, built around the TPS62740DSS and MMBF170. 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 SSatH/SSatH repository on GitHub, at the commit this page was made from: the board is 04-Layout/SS@H001/SS@H001-0/SS@H001.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 SSatH before reusing the design.
