Alen.ATLow WROTE:Can we connect the USB cable and and External 12V supply to the main board together? It seems shorting my USB when I connect it in such a way.
Alen.ATLow WROTE:I wonder can we improve this by applying forward bias diode to prevent the voltage flow from higher potential to lower potential source of both USB and External Power supply.
Bricking up Mega is not a big pain compare to having out USB port burn up. haha
