EFR32MG12 Series 1 Modules

EFR32MG12 Series 1 modules integrate the EFR32MG12 Mighty Gecko SoC into a small form factor module for Zigbee, Thread and Bluetooth Low Energy (BLE) networks. With up to 1024 kB of Flash and 256 kB of RAM, EFR32MG12 Series 1 modules are ideal for applications that require multiple protocols and lower volume (<100 K) applications, enabling fastest time to market. The fully certified modules integrate all components (crystals, RF passives and antenna) required for a system-level implementation of Zigbee, Thread and BLE networks. With +10 dBm and +17 dBm versions, the modules meet worldwide regulatory requirements for IEEE 802.15.4 2.4 GHz used in both Zigbee and Thread networks, as well 2GFSK used in BLE networks.
