Direct Connection with Jumpers on Leonardo

If you have a Leonardo we have to do a funky trick where we swap the Direct connect wires

(because the processor chip acts like the USB/Serial converter rather than having a seperate chip.

The upshot is you'll need two wires. For basic testing as long as the wires touch the two sets of

pads, you'll be able to continue with this very basic test. We don't suggest soldering them yet in

since as long as the GPS works, you can go forward and use software serial if you prefer

Select Software Serial on the switch. Connect a wire from the TX pad to digital 0 and a wire from the

RX pad to digital 1.
