Note that the bill of materials (BOM) and other technical documents can be opened in OpenOffice format and PCB files are in EAGLE format, but they can also be opened and edited in the open source Kicad program. One version is provided for each board, Rev C are fully tested boards, put into limited production and used on a 72VDC electric scooter named Fido, and a 150VDC VW bug conversion, and other EV projects.
