34 parts, built around the B0505S-1WR3, SN75176AP and FT232RL. 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 szzazi/USB-DMX-interface repository on GitHub, at the commit this page was made from: the board is USB-DMX-interface.kicad_pcb and its schematic USB-DMX-interface.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 szzazi before reusing the design.
