QSG166: WF200 Wi-Fi Development Kit
Quick Start Guide
The WF200 Wi-Fi Development Kit is an excellent way to get star-
ted with WF200 Wi-Fi transceiver IC to achieve performance eval-
uation and software development.
It supports various hardware and software use cases, as described below.
Two versions of devkits are available:
• SLEXP8022A contains WF200 development board (BRD8022A), that can be connec-
ted to Silicon Labs EFM32 Starter kits (STK3701 for GG11) or to a Raspberry Pi for
the Linux case. It also contains a micro-SD card allowing fast startup with a Raspber-
ry Pi.
• SLEXP8022B is a superset of SLEXP8022A with a Raspberry Pi 2 model V1.2 inclu-
ded.
This document described the first steps to get a Wi-Fi connection for the Linux case
(Raspberry Pi), Silicon Labs MCUs, as well as a case with a 3rd party MCU.
Note: Refer to
UG379
for more details about the board.
