Looking for suggestions to battery power source XBee Pro modules:

  1. I am supposed to use three 1.5 battries (AA batteries) along with a 3.3V regulator chip to power the XBee Pro ?
    which regulator should I be using in this case ?

  2. or I am supposed to use a 3.3V battery to power XBee Pro ?
    in this case which battery should I order ?

I'll be using Xbee Pro in combination with Arduino mini pro (3.3v i believe)

Any other ideas appreciated too

TIA !
