MGM12P Mighty Gecko Multi-Protocol
Wireless Mesh Module Data Sheet
The Silicon Labs Mighty Gecko Module (MGM12P) is a fully-inte-
grated, certified module, enabling rapid development of wireless
mesh networking solutions.
Based on the Silicon Labs EFR32MG12 Mighty Gecko SoC, the MGM12P combines an
energy- efficient, multi-protocol wireless SoC with a proven RF/antenna design and in-
dustry 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.
MGM12P can be used in a wide variety of applications:
•
•
•
•
•
•
