This is the most advanced and competitive XBee interface board you will find! It's breadboard compatible, has 4 status LED's (one selectable to display ASC or RSSI), built-in 3.3V power regulator, configuration solder jumpers and an unique feature that allows you set the device as Master or Slave FTDI mode with a simple slide of a switch!

In master mode you will be able to attach any USB FTDI cable/board and send/receive data like the rest of the average XBee adapters do (normal use mode), but if you slide the switch to "Slave mode" you will be able to attach the XtreamBee to any FTDI compatible device, like Arduinos, ArduIMU and Ardupilots. So you only need two XtreamBees, to create the Master-Slave connection enabling two-way wireless FTDI communication  (or one XtreamBee set in "Slave Mode", if you already have another third party XBee adapter). You can even tweak the board to emulate in a wireless fashion a  CTS and RTS signals. This board was under development for about 1.5 years! After many failures, I was finally able to make it work with cheap/passive components. Great isn't it?
