Series 2 XBee "ZigBee" modules is the Zigbee XBee Module S2C - 2mW with Wire Antenna - XB24CZ7WIT-004. 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.

This version (S2C) of XBee ZigBee Series 2 module utilizes EM357 transceiver. The EM357 transceiver is faster, has the lower current draw, and has significantly more RAM and Flash. These advanced features allow EM357-based modules to support more network traffic, have more memory for code updates, and operate more efficiently.

These are ideal for applications in the energy and controls markets where manufacturing efficiencies are critical. For current customers interested in taking advantage of these performance improvements, the XBee Zibee migration guide will assist with migrating from S2B XBee ZigBee modules to the S2C XBee ZigBee modules.
