The E-blocks ZigBee board uses a V2 XBEE module to allow you to connect one or more E-blocks systems together using the new ZigBee (wireless area network) standard, or to connect your system to a third party ZigBee system. The modules used are compliant with the 2007 ZigBee Pro standard. Because of the nature of the ZigBee standard there are two different boards the EB051R is preprogrammed to behave as a router node in a ZigBee system. The EB051C is preprogrammed to behave as a co-ordinator node in a ZigBee system. Flowcode macros for this E-blocks board are available.
