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.
KEY FEATURES
Based on the Silicon Labs EFR32™ Mighty Gecko SoC, the MGM111 combines an ener-
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.
• Industry-leading mesh networking (ZigBee/
Thread) software and development tools
• Antenna: internal chip and U.FL variants
• TX power: up to +10 dBm
• RX sensitivity: down to -99 dBm
• 32-bit ARM® Cortex®-M4 at 40 MHz
• Flash memory: 256 kB
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:
• RAM: 32 kB
• Autonomous Hardware Crypto Accelerator
and Random Number Generator
• Connected Home
• Building Automation
• Lighting
• Integrated DC-DC Converter
• Security and Monitoring
• Smart Grid / Metering
• Industrial Automation
• Others
