How to Power up with 12V at Vin and use serial OP

Post by platypus » Thu May 30, 2013 7:57 am

Is it possible to powerup the ethermega/Eleven via 12V at Vin/Gnd and still output data via the USB to serial monitor - it doesn't look like it as there is no serial port seen when using external power.

I would like to send data out to the PC via serial but powerup usingVin/Gnd.

I don't want to use the PC usb to powerup the board.
