UG407: WFM200S Wi-Fi
®
Expansion Kit
User's Guide
The WFM200S Wi-Fi Expansion Kit is an excellent way to ex-
plore and evaluate the WFM200S Wi-Fi Transceiver Module with
a Raspberry Pi or an EFM32 MCU for your embedded applica-
tion.
The WFM200S Wi-Fi Transceiver 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 pro-
tocol stack is offloaded to the NCP and allows for easy Wi-Fi integration into any em-
bedded system.
The kit easily integrates and brings Wi-Fi connectivity to a compatible Silicon Labs
MCU Starter Kit through the EXP header. The WFM200S Wi-Fi Expansion Kit has also
been designed after the Raspberry Pi Hardware Attached on Top (HAT) board specifi-
cation, allowing the WFM200S Wi-Fi Expansion Kit to connect to a Raspberry Pi.
