T BRIEF 

## **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** 

   - **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** 

## _**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.
