The Arduino V0.3 XBee PRO shield features a stackable design which makes it more convenient to connect with other expansion boards. It solves the problem of the previous version not being able to match some other expansion boards.
Features: • This Arduino XBee shield allows the Arduino to communicate wirelessly over a modified ZigBee protocol using the popular XBee module. • It is a fully Assembled shield without the XBee module. • It works with all XBee modules including series 1, series 2.5, standard and PRO versions.
On V0.3 a switch has been added to select Xbee or USB mode instead of jumpers (like on the previous V0.2 version), which is much more convenient to use!
