Is it possible to power the Seeeduino Mega v3.0 with an external 5V source? Should I connect this 5V directly to the 5V and GND headers?
When done so, can I then connect the USB or will this break the board or USB port?
Note: A similar question was asked for the 1.23 version but that answer cannot be applied to version 3.0 because the power circuits between these versions are quite different.
thanks in advance,
