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.
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 Limited
AP (embedded web pages) or Wi-Fi
Protected Set-up (WPS)
•
Ultra low power consumption through
dynamic power management
o
Sleep, Deep Sleep, Standby
FEATURES:
•
Operates with standard 802.11 b/g/n access
points at speed up to 11 Mbps (802.11b)
− Infrastructure, Limited AP or Adhoc
•
Two serial UART ports
− Data rates of up to 921.6kbps
•
Two SPI ports
− Supports SPI Master/Slave modes
− Data rate of up to 3Mbps
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.
