Returning Products to GainSpan
If a problem cannot be resolved by GainSpan technical support, a Return Material
Authorization (RMA) is issued. This number is used to track the returned material at the
factory and to return repaired or new components to the customer as needed.
To return a hardware component:
1. Determine the part number and serial number of the component.
2. Obtain an RMA number from Sales/Distributor Representative.
3. Provide the following information in an e-mail or during the telephone call:
– Part number and serial number of component
– Your name, organization name, telephone number, and fax number
– Description of the failure
4. The support representative validates your request and issues an RMA number for
return of the components.
5. Pack the component for shipment.
Guidelines for Packing Components for Shipment
To pack and ship individual components:
– When you return components, make sure they are adequately protected with
packing materials and packed so that the pieces are prevented from moving
around inside the carton.
– Use the original shipping materials if they are available.
– Place individual components in electrostatic bags.
– Write the RMA number on the exterior of the box to ensure proper tracking.
NOTE: Do not return any components to GainSpan Corporation unless you have
first obtained an RMA number. GainSpan reserves the right to refuse shipments
that do not have an RMA. Refused shipments will be returned to the customer by
collect freight.
CAUTION! Do not stack any of the components.

NOTE: Modules ship with test code ONLY. Designers must first program the
modules with a released firmware version. Designers should bring out GPIO27
pin (option to pull this pin to VDDIO during reset or power-on) and UART0 or SPI0
pins to enable programming of firmware into the module. For details refer to the
Programming the GainSpan Modules document.

Chapter 1 GS2011M Overview
This chapter describes the GainSpan® GS2011M low power module hardware specification
overview.
• Product Overview, page 19
• GS2011M Module Product Features, page 19
1.1 Product Overview
The GS2011M low power based module provides cost effective, low power, and flexible
platform to add Wi-Fi connectivity for embedded devices for a variety of applications, such
as wireless sensors and thermostats. It uses GS2000 SoC, which combines ARM® Cortex
M3-based processors with a 802.11b/g/n Radio, MAC, security, and PHY functions, RTC
and SRAM, up to 4 MB FLASH, and on board and off module certified antenna options.
The module provides a Wi-Fi and regulatory certified IEEE 802.11b/g/n radio with
concurrent network processing services for variety of applications, while leverage existing
802.11 wireless network infrastructures.
1.2 GS2011M Module Product Features
• Family of modules with different antenna and output power options:
• GS2011MIx 22.8mm (0.90in) x 32.5 mm (1.28in) x 3.63mm (0.143in) 48-pin
PCB Surface Mount Package. Two SKU’s are:
– GS2011MIZ (on-board antenna)
– GS2011MIE (external antenna)
• The two SKUs are pin to pin compatible, and the user has to account only for
power consumption, and on-board antenna keep out (if used) to accommodate
“one size fits all” for various end applications.
• Simple API for embedded markets covering a large range of applications
• Fully compliant with IEEE 802.11b/g/n and regulatory domains:
– 802.11n: 1x1 single stream, 20 MHz channels, 400/800ns GI, MCS0 – 7
– Data rates of 7.2, 14.4, 21.7, 28.9, 43.3, 57.8, 65.0, 72.2 Mbps
– 802.11g: OFDM modulation for data rates of 6, 9, 12, 18, 24, 36, 48 and 54
