MSP432P401R: Powering MSP432 externally

Part Number: MSP432P401R

Hello,

I want to connect the MSP432 by an external power supply.

Shall I use a 5v dc battery connecting to j7 or a 3.3v battery to J6 ?

Are there any other changes that needs to be done on MSP432 for connecting to external supply instead of USB laptop supply?

My msp432 is connected to a CC3100 wifi booster back too.
