Omega 1 - Expansion board - external power supply problem

  • Hi,
    I got problem with my omega 1 when I try power it from external power supply ..

    I got Omega on expansion board, omega looks like booting, after about 30s omega amber led stay solid light. But no Wifi, and I'm not able to connect via serial šŸ˜ž

    I try connect 3,3V to 3,3V pin on expansion dock GND to GND - same issue
    I try connect 5V to 5V pin on expansion dock GND to GND - same issue
    I try connect just one (5V or GND and power it from usb) same issue

    If I disconnect it from external supply GND and 5V and plug in USB it boot correct.

    If I have connected one of external power supply cable (GND or 5V/3V) and cycle power with usb connected, in putty I got just mess characters

    As power supply I use :
    arduino breadboard power supply .

    Any suggestion ? THanks

  • Hm, It look like my device what is connected to GPIO (5V 8 Channel Relay Module Board For Arduino PIC AVR DSP ARM) drain a lot of power by GPIO šŸ˜ž

    But why ?
