It measures 50 × 40 mm and has 4 copper layers, 1.58 mm thick.
95 parts, built around the MS5611-01BA03, MT3608B, W25Q32JVSSIQ and DW01A. 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 tomatencode/Alacer-1 repository on GitHub, at the commit this page was made from: the board is Alacer-1.kicad_pcb and its schematic Alacer-1.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 tomatencode before reusing the design.
