2 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 mayyyk/RC_filter_PCB_circuit repository on GitHub, at the commit this page was made from: the board is RC_filter.kicad_pcb and its schematic RC_filter.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 mayyyk before reusing the design.
