Digi’s XBee ZB module and the EM260 co-processor are similar in many respects. Both are designed toprovide an interface to a ZigBee¨ network while allowing external applications to be developed aroundtheir interface. The EM260 offers cheaper hardware than the XBee and provides access to the lowestZigBee functions. Designing around the EM260 requires some RF design and additional regulatory testing(FCC, ETSI, etc.) than is required of an XBee-based design.
