UG291: WGM110 Wi-Fi® Expansion Kit
User's Guide
The WGM110 Wi-Fi Expansion Kit is an excellent way to explore
and evaluate the WGM110 Wi-Fi Module with an EFM32 MCU for
your embedded application.
The kit contains a Wireless Expansion Board (BRD8016A) and a WGM110 Wi-Fi Mod-
ule Radio Board (BRD4320A). The WGM110 Wi-Fi Module is an easy to use and easy
to interface Wi-Fi Network Co-Processor (NCP). Most of the associated complexity of
Wi-Fi and the protocol stack is offloaded to the module and allows for easy Wi-Fi inte-
gration into any embedded system.
The kit easily integrates and brings Wi-Fi connectivity to a compatible Silicon Labs
MCU Starter Kit through the expansion header. The Wireless Expansion Board has al-
so been designed after the Raspberry Pi Hardware Attached on Top (HAT) board speci-
fication, allowing the WGM110 Wi-Fi Expansion Kit to connect to a Raspberry Pi.
