GainSpan GS1011MxxS,
Size-Optimized Low Power
Wi-Fi® Module Family
PRODUCT OVERVIEW
The GS1011MxxS family of size-optimized, fully certified modules offers
a quick, easy and cost effective way for device and appliance
manufacturers to add Wi-Fi capabilities to their products, while offering a
smaller footprint for space constrained application boards. The module
dimensions are 28.7mm * 19.4mm, resulting in board area savings of
approximately 34% when compared to the GS1011MEx modules. The
GS1011MxxS modules provide multiple serial UART or SPI interfaces,
enabling connection to embedded designs utilizing an 8/16/32-bit
microcontroller, via simple commands. These are lower pin-count
modules (36 pins) compared to full-featured GS1011Mxx modules (48
pins). The GS1011MxxS 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/g/n
wireless networks 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 full Wi-Fi and TCP/IP
networking stacks, completely offloading the host. In addition, it supports
WEP/WPA/WPA2 Security, Ad-hoc and Limited AP modes as well as Wi-
Fi Protected Setup (WPS) for ease of provisioning.
BENEFITS:
•
Brings Wi-Fi and web connectivity to
any device with a microcontroller and
serial HOST interface (UART or SPI)
Reduces development time, testing and
certification burden, accelerating time
to market
Fully contained solution minimizes
host processor loading when needed
Easy device provisioning through Ad-
hoc, Limited AP modes or Wi-Fi
Protected Set-up (WPS)
Ultra low power consumption through
dynamic power management

GS1011MxxS Based Embedded Design
The module family consists of three different SKUs for antenna
configuration and output power. The module SKUs 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.
