I have a rev 1D.4 motherboard. Will it not work?

    administratorPosted on7:59 pm - Jul 12, 2019

    Apart from dimensional difference 1D4 mainboard has different connector, ergo USB module for 2B will not work with 1D4 mainboard without major modification.
    USB module for 1D4 mainboard is beeing redesigned now and should be available (again) in about 4-5 weeks.
