EFR32MG1 Based Modules (Series 1)

EFR32MG1 Series 1 modules integrate EFR32MG1 Mighty Gecko SoCs into a small form factor module for Zigbee and Thread mesh networks. EFR32MG1 modules enable the fastest time to market and are ideal for lower volume (< 100 K) applications. This fully certified module integrates all components (crystals, RF passives and antenna) required for a system-level implementation of Zigbee and Thread mesh networks. At +10 dBm this module meets the worldwide regulatory requirements for IEEE 802.15.4 2.4 GHz used in both Zigbee and Thread networks.
