SPZB250 is a low power consumption ZigBee module based on EM250 ZigBee system-on-chip which integrates a 16-bit processor together with a 2.4 GHz, IEEE 802.15.4-compliant transceiver as well as IEEE 802.15.4 PHY and MAC. It enables OEMs to easily add wireless networking capability to any electronic device. Such a module is a very comprehensive solution to build wireless sensors with meshing and self-healing capability as required in a WSN scenario.
