XBee Pro S2B in AT mode keeps resetting the Arduino
Is the Arduino board's regulator rated for the XBee Pro's current draw?

I know Sparkfun had some issues with this, where their XBee -> computer interface board had a 150ma 3.3v regulator, and the XBee Pro needs ~ 215mA.

If the 3.3V regulator is too small, the XBee could be browning-out the local power supply as it tries to power on.



How are you connecting the XBee to the Arduino board anyways? From what I could see looking up the Freetronics board you mentioned, it doesn't have an XBee socket.
