We now carry the Series 2 XBee "ZigBee" modules. This is the series 2 ZigBee protocol 1mW with wire antenna. Its good for point-to-point, multipoint and mesh networks. This module is a little more difficult to get going than the Series 1 - you must set up a "coordinator" module so they are not as plug-and-play.
Series 2 modules cannot talk to Series 1 modules so if you already have some S1 type XBees you may want to stick with them. The S2 modules are not necessarily 'better' than S1 for many projects. They're just different as they use the "ZigBee" wireless stack instead of the 802.15.4. This makes them better for low power usage and advanced users who want a mesh topology (many XBees in a spread-out configuration) - but they are more difficult to use for basic point-to-point setups.
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.
This module comes with a wire antenna, its the same price as a chip antenna but 50% more range because of the improved antenna, awesome!
