This is the XBee XBP24-BZ7WIT-004 module from Digi. These are often called Series 2 modules, it may not be the correct term, but it does distinguish these from the Series 1 modules. They can run in a transparent mode or work with API commands. They can also run in a mesh network making them highly configurable and awesome modules. Series 2 improves on the power output and data protocol. Series 2 modules allow you to create complex mesh networks based on the XBee ZB 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.
These are essentially the same hardware as the older Series 2.5, but have updated firmware. They will work with Series 2.5 modules if you update the firmware through X-CTU
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 2 XBee modules have exactly the same pin-out. However, Series 1 modules cannot communicate with Series 2 modules.
Note: If you are using these outside, please check with your local laws regarding radio communication.
