This is the Pro (higher-power) version of the popular XBee! This module is series #1 (802.15.4 protocol) 60mW wireless module, good for point-to-point, multipoint and convertible to a mesh network point. These are much more powerful than the plain XBee modules, great for when you need more range.

What we like about the Series 1 modules is that they are so easy to get set up. If you have two in range, they will automatically form a serial link with no configuration, so you can send TTL serial data back and forth. You can also configure the baudrate, as well as sleep modes, power modes and tons more stuff using the Digi XBee tool.

The pins on an XBee are 2mm spacing, not 0.1" so they will not fit into a breadboard. For that reason, they work best in our XBee adapter module kit (which has a 250mA 3.3V regulator) or with the USB XBee adapter.
