6 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 terenceang/DB192IDC20 repository on GitHub, at the commit this page was made from: the board is PCB/DISK2BREAKOUT/DISK2BREAKOUT.kicad_pcb and its schematic PCB/DB192IDC20/DB192IDC20.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
