This is the new 2.4GHz XBee XB24-BCIT-004 module from Digi (formally Maxstream). Series 2.5 improves on the power output and data protocol. These modules take the 802.15.4 stack (the basis for Zigbee) and wrap it into a simple to use serial command set. 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.
Please Note: Series 1 and Series 2.5 XBee modules have the same pin-out. However, Series 1 modules cannot communicate with new Series 2.5 modules.
