m3pi schematic diagram of the serial connections between the various components.
The unused Wixel and XBee pins are connected together as shown in the diagram below. It is not
possible to simultaneously use a Wixel and XBee, so these connections exist to provide more multiple
convenient access points for each of the unused Wixel and XBee pins.
