KeySpecifications:
Power Requirements: 6 to 30 VDC (6 to 15 VDC recommended)
Communication: Serial
Dimensions: 4.00 x 3.00 x 0.65 in (102 x 76.2 x 16.5 mm)
Operating Temperature: -40 to +185 °F (-40 to +85 °C)


I assume I can just plug in a 12v power source from the car battery (knowing it may get up to 14.4v when running)

I also assume that I should solder the wires to the board next to the 9v battery plug on the Vss and Vin connections ?

Thanks,

The Super Carrier has both a clip for a 9 volt battery and a barrel connector for other sources. They are physically arranged so only one or the other can be used at one time.

Within the capability of the voltage regulator ( it can get very warm with high input voltage and modest current consumption) any input voltage from 8 to 30 VDC will work fine. I changed the regulator on mine to a switchmode type ( PT5101N ) to minimize the heating concerns.

Cheers,
