Software configurable RAW power through V1 or V2 #12

These regulators have the ability to take 20V and can output up to 13.8V. I'm thinking if we specified that the tech power the test-bed with enough voltage, we could add in another resistor value that would output around 7V (or more), which in most cases is a sufficient RAW voltage supply for a board with a regulator. This would allow for RAW voltage to be output from the regulator using just software, eliminating the need to reconfigure the RAW jumper for that switch. We could leave the jumper for cases that require more than 13.8V. Not sure how much those mosfet's can handle, I think it's around 25V.

Sounds great. Let's think about using some more GPIO and possibly having 7V and 9V as selectable.

Decided to not include this, RAW is routed through the header, and a power control circuit can be added to the daughter board if we do need to supply over 5V.
