The Major Differences in the XBee Series 1 vs. the XBee Series 2

The two most common RF radios that are available from Digi are the Series 1 and Series 2 XBee. The Series 1 and Series 2 modules are quite similar, but selection of a module should be based upon application specific needs.

All XBee radios have the same footprint and for the most part-are pin for pin compatible (with a few differences in the placement of ADC/IO lines), but are NOT interoperable. Series 1 and Series 2 use different application profiles, which are unique to each radio family. They can however, use the same RS232 or USB interface boards.

Since hardware specifications are similar, the differences between XBee Series 1 and 2 are more evident in the firmware features. Listed below are some of the more defining differences in the firmware:

A study of the product manuals to compare the Series 1 and Series 2 radios more completely is left to the user. However, Digi Applications Engineers are available to discuss these differences in greater detail, and can be reached at 1-801-765-9885.
