MGM111 Mighty Gecko Mesh Networking

Module Data Short

The Silicon Labs Mighty Gecko Module (MGM111) is a fully-integrated, pre-certified

module, enabling rapid development of wireless mesh networking solutions.

gy-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.

MGM111 can be used in a wide variety of applications:
