147 parts, built around the SGTL5000XNLA3, AP7361C-33E, USBLC6-2P6 and XC6206P182MR. 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 FerretCode/ns-1 repository on GitHub, at the commit this page was made from: the board is hardware/ns-1.kicad_pcb and its schematic hardware/ns-1.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 FerretCode before reusing the design.
