1. Product introduction

1.1 Overview

This is a complete WiFi module which is designed for embedded wireless solution and a cost-effective, low power
capabilities high performance MCU in M2M applications. It includes standards-based wired and wireless
technologies to enable IP infrastructures for smart grid, smart home, security, building automation, toys, robots,
remote health and wellness monitoring and other M2M applications.

The module integrates ARM CortexTM-M3 MCU, WIFi and front end into a smallest form factor LGA package. It is
based on Broadcom IEEE802.11 b/g/n antenna diversity single-stream Broadcom align technology. Thus, it can be
used to enable wireless connectivity to the simplest existing sensor products with minimal engineering effort.

The solution is provided as a module to reduce development time, lower manufacturing costs, save board space,
ease certification, and minimize RF expertise required. Additionally it is provided as a complete platform solution
including software drivers, sample applications, API guide, user documentation.
