All hardware design is published as KiCAD files. You can ask some manifactures to build them. If you are customer of JLCPCB, Elecrow, FusionPCB, or PCBWay, you can find the zip files including everything to build PCB in here. For PCBA, BOM and Pos files are here. All parts are available in Mouser (2024 Oct. 24).
