55 parts, built around the 74HC237. 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 DavidMFlynn/SimpleServoCtrl16 repository on GitHub, at the commit this page was made from: the board is SimpleServoPS_PCB/SimpleServoCtrl.kicad_pcb and its schematic SimpleServoPS_PCB/SimpleServoCtrl.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 DavidMFlynn before reusing the design.
