This Xbee shield includes a 3.3V regulator, a signal conditioning system, and basic activity indicators (Power, RSSI and DIN/DOUT activity LEDs).
It translates the 5V serial signals to 3.3V so you can connect a 5V (down to 3.3V) system to any XBee module. The board was conveniently designed to mate directly with Arduino Pro boards for wireless boot loading and USB based configuration.
This unit works with all XBee modules including the XBee Series 1 and 2, XBee standard and XBee Pro versions. Plug an XBee into this breakout and you will have direct access to the serial and programming pins on the XBee unit and you will be able to power the XBee with 5V.
This board comes fully populated with 3.3V regulator (16V max input), XBee socket, four status LEDs, and level shifting. In the latest revision the diode level shifter is replaced with a more robust MOSFET level shifter.
Can be connected with XBee Series1 and Series2 Series Standard Edition and Professional Edition module
