Hi,

my board stop working and now dosen't want to power up anymore. Even the three leds don't want to power on too. When I plug the USB, the main chip start to heats a lot and I detected a shorted circuit through 3.3V and GND. What`s happend? If I desconnect the jumpers between JP1, JP2 and JP3 I can plug the USB normally. Anyway, there's nothing connected to the board right now and it still not working or power up when I plug the USB.

    Hi Gabriel,

    It sounds like the board has been damaged. Have any modifications been made to the board? Do you have a access to a thermal cameral, this may help you to see what devices on the board are damaged and replace the components appropriately

    Regards,

    Peter
