This is the XBee XBP24BZ7SIT-004 module from Digi.
The new Series 2B improves upon the power output and data protocol of the Pro Series2.
Series 2B modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware.
These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port!
Point to point and multi-point networks are supported.

Series 2B modules use a different hardware configuration from the earlier models and while they will communicate with Series 2 XBee modules, they are not compatible with the outdated Series 2.5 Modules.

Note: If you are looking for a simple point-to-point configuration, you might want to try the Series 1 instead. The Series 2 requires considerable setup and configuration.

Note: Series 1 and Series 2B XBee modules have the same pin-out. However, Series 1 modules cannot communicate with Series 2B modules.

Note: If you are using these outside of the United States, please check with your local laws regarding radio communication.
