3. System Overview
3.1 Introduction
The WGM160P module combines the WF200 Wi-Fi transceiver with an EFM32GG11 microcontroller to deliver a complete and certified
standalone Wi-Fi solution, with the ability to run customer application on an Cortex M4 processor.
This device supports Gecko OS, a comprehensive software solution that simplifies the Wi-Fi , application and cloud connectivity devel-
opment process to reduce time to market. For more details on the software platform, please consult our online documentation.
