XBee ZB / ZigBee modules provide cost-effective wireless connectivity to devices in ZigBee mesh networks. Utilizing the ZigBee PRO Feature Set, these modules are interoperable with other ZigBee devices, including devices from other vendors. The most common factor in determining whether to use ZB is the potential need to tie-in with other ZigBee-compatible networks or mesh networking. If this is not a requirement, the series 1 802.15.4 modules may be perfectly suitable for your project.
Note: Because XBee modules have 2 mm pin spacing, we recommend one of our adapter boards for each module. Our adapter boards provide several advantages to the XBee modules such breadboard-friendly standard 0.1 inch pin spacing, mounting holes, and easy-to-solder connections. Even if you are communicating point-to-point without a PC, we still recommend that you always have at least one XBee USB Adapter Board (# 32400) so you can easily configure and test each XBee module prior to putting it in a point-to-point application.
