The GS2011M module by GainSpan provides a quick and easy way for device and appliance manufacturers to add Wi-Fi connectivity to their products. It adds low-power, high-speed Wi-Fi and internet connectivity to any device with a microcontroller and serial host interface.

The module provides a high-speed serial interface connection to an embedded design built on an 8/16/32-bit microcontroller, achieving up to 40 Mbps throughput over an SDIO interface. It is suitable for organisations with limited Wi-Fi or RF expertise or seeking faster time to market, as it reduces RF design time and removes the burden of testing and certification.

The module includes two analog to digital converter (ADC) pins for connecting energy measurement and other sensors. It runs the full Wi-Fi and TCP/IP networking stacks on module, offloading the host microcontroller. The module supports a complete suite of security protocols, also without tasking the host microcontroller, including WPA/WPA2-Enteprise and Personal security modes, legacy WEP encryption and upper layer security protocols such as TLS/SS and HTTPs. Alternatively, it can be run self-contained without a host.

For ease of provisioning, the module can be set up from a smartphone or laptop through the Limited AP mode or with Wi-Fi Protected Setup (WPS). It has extended range with good receiver sensitivity and is available with a u.FL connector to add an external antenna for high performance or a ceramic chip antenna for performance and convenience while saving space.

The module is US/Canada (FCC/IC), Europe (ETSI) and Japan (TELEC) certified; IEEE 802.11b/g/n compliant with PHY rates up to 72 Mbps; and meets worldwide regulatory and Wi-Fi Alliance certification requirements. It is footprint- and pin-compatible to GS1011M and GS1500M modules.
