Mighty Gecko Mesh Modules Silicon Labs Mighty Gecko Mesh Modules are built on the Silicon Labs EFR32 Mighty Gecko SoC family and are designed to enable Zigbee, Thread, and multiprotocol networks. These small form factor mesh modules allow fast time-to-market and are ideal for lower volume (<,100K) applications. The fully certified Mighty Gecko integrates all components (crystals, RF passives, and antenna) required for a system-level implementation of Zigbee and Thread mesh networks. At +10dBm and +17dBm, these modules meet the worldwide regulatory requirements for IEEE 802.15.4 2.4GHz used in both Zigbee and Thread networks.
