It measures 78.7 × 31 mm and has 2 copper layers, 1.6 mm thick.
16 parts. 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 avnguyen08/Work_SSS repository on GitHub, at the commit this page was made from: the board is Version_A/Top_Board/Top_Board.kicad_pcb and its schematic Hardware_Filter_SSS/Hardware_Filter_SSS.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 avnguyen08 before reusing the design.
