Introduction

The Silicon Labs Mighty Gecko Module (MGM111) is a fully-integrated, pre-certified module, enabling rapid development of wireless mesh networking solutions. Based on the EFR32 Mighty Gecko SoC, the MGM111 combines an energy-efficient, multi-protocol wireless SoC with a proven RF/antenna design and industry-leading wireless software stacks. This integration accelerates time-to-market and saves months of engineering effort and development costs. In addition, common software and development tools enable seamless migration from a module to discrete SoC-based design when the time is right.
