XBee 3 Zigbee 3.0 supports the full Zigbee 3.0 specification and remains backward compatible with Zigbee PRO, ensuring legacy and new devices can coexist in the same mesh network. Its MicroPython scripting environment lets developers run edge logic directly on the module, reducing host MCU overhead. Over-the-air firmware updates keep deployed devices current without physical access. The module’s sleep modes achieve as low as 1.5 μA current draw, extending battery life in remote sensor nodes. Digi’s XCTU configuration software provides a graphical interface for network testing and firmware management.
