The wiring can be found [here](http://wiki.minnowboard.org/MinnowBoard_MAX_HW_Setup).<br> +Up Boards use the same FDDI 3.3V adaptor than the Minnow but the pin out is not adjacent and requires to split the pins. On the Joule the serial connection is done via the micro USB cable which is not provided in the Developer kit. Details can be found [here](https://software.intel.com/en-us/node/667851).
