    Microhard pDDL Carrier USB Dongle + Microhard pMDDL2450 2.4GHz MIMO Digital Data Link
    Accidental overvoltage damage (7.4V).

    I'm still able to access the WebUI and apply settings.
    The RX LED is solid green.
    No radio activity (as expected)

    My question is: Which component do you believe is damaged, the carrier board or the modem? Or both?
    Do you think that either is salvageable?

    Thanks!
    Chad

      Hi @Chad-Zulu
      Sorry to hear about that.
      Most likely both modem and the M0048 carrier board are permanently damaged.

      There are several components on M0048 that are rated for 6V ABS max, and according to MH they only tolerate 5.5V on their modem device.
