77 parts, built around the 74HCT240D, PCF8574P, BC337 and BC546. 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 m47eus2/SunCommander-PCB repository on GitHub, at the commit this page was made from: the board is pcb/SunCommander-RelayModule/SunCommander-RelayModule.kicad_pcb and its schematic pcb/SunCommander-RelayModule/SunCommander-RelayModule.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
