GainSpan GS1011M Low

Power Wi-Fi® Module Family

PRODUCT OVERVIEW

The GS1011M family of fully certified modules offers a quick, easy and

cost effective way for device and appliances manufacturers to add Wi-Fi

capabilities to their products. The module provides multiple serial UART

or SPI interfaces, enabling connection to any embedded design utilizing a

8/16/32-bit microcontroller via simple commands. The GS1011M is an

ideal solution for organizations with limited or no Wi-Fi or RF expertise,

as it not only dramatically reduces RF design time but also removes the

burden of testing and certification, allowing customers to focus on their

core application, product or expertise. The module supports data rates up

to 11 Mbps, is compliant with 802.11b and meets regulatory and Wi-Fi

Alliance requirements.

Multiple software configurations are available for the stack running on

the module. For applications utilizing a small 8 bit microcontroller host,

the module supports a serial to Wi-Fi function and runs the full Wi-Fi and

TCP/IP

networking

stacks,

completely

offloading

the

host.

For

applications utilizing more powerful microcontrollers, the networking stack

and services can reside on the host while the module provides the IP to

Wi-Fi functionality. In addition, it supports WEP/WPA/WPA2 security,

Adhoc as well as Wi-Fi Protected Setup (WPS) for ease of provisioning.

GS1011M based Embedded Design

The module family consists of four different SKU’s for antenna

configuration and output power. The module SKU’s are single sided, pin

compatible with castellation on the edges for I/O connection so module

can be soldered down on customer application base-board.
