Description

XBee is a wireless communication module that Digi built to the 802.15.4/ZigBee standard. The beauty of the 802.15.4/ZigBee wireless standard is that it can form self-healing mesh networks. These are great for making a wireless control network that spans from one corner of your house to the other.

By default, the modules are configured from the factory to be a wireless serial line replacement. It can be programmed to do other functions like behave as a "wireless wire" where a level transition on an input pin of one module is sent out as the same level transition on a different module output pin. There is also a special API mode, where the modules accept bytes of data from the host to transmit into the network.

There are two versions of the Xbee modules; 802.15.4 (DigiMesh 2.4) ) and ZB ZigBee. The difference being that the ZB modules are compatible with normal ZigBee networks, where the DigiMesh is a proprietary mesh solution. Each version comes in 2 flavors: XBee and XBee-Pro. The XBee-Pro modules have a more powerful radio, thus have a longer range.
