Power inputs

All,
I can't locate the information on the 3 ways to power it right now.

If I use the BATT+ and BATT- can I use up to 9 volts?

When should I use VIN as opposed to 5V as input?

Thanks.

Hi hitchcock4, whenever using Vin on an arduino you are connecting to the input and ground of the voltage regulator. You should be able to apply up to 18v to Vin, so you will certainly be fine with 9volts.

You would use the 5v input if you have a circuit that already has its own regulator that is supplying 5v :)
