MGM111 Mighty Gecko Module for Zigbee and Thread

Silicon Labs’ Mighty Gecko MGM111 module integrates our EFR32MG1 Mighty Gecko SoC into a small form factor module for zigbee and Thread mesh networks. Modules enable the fastest time to market and are ideal for lower volume (< 100 K) applications. The 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 WW regulatory requirements for IEEE 802.15.4 2.4 GHz used in both zigbee and Thread networks.

Module Benefits

  • Built on Silicon Labs Wireless Gecko SoC family
  • Up to 109 dBm link budget
  • Internal chip antenna and external antenna (U.FL) variants
  • Provides rapid time-to-market with onboard stack, antenna and regulatory certifications
  • Supported by Silicon Labs reliable, secure and flexible mesh protocol stacks
  • Uses same development tools as the Mighty Gecko ICs; Simplicity Studio, Energy Monitor, Packet Trace
  • Can support SoC or network co-processor architectures
  • Provides customers with an easy upgrade path to a discrete SoC design
