58 parts, built around the PCF8574AP, 74HC4051 and WS2812B. 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 PMheiilsDev/midi_test repository on GitHub, at the commit this page was made from: the board is _pcb/main_pcb/main_pcb/main_pcb.kicad_pcb and its schematic _pcb/main_pcb/main_pcb/ADC.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 PMheiilsDev before reusing the design.
