Small, Low-Cost Wi-Fi Modules for the Internet of Things introduced bij GainSpan

While small, the GS1011MIxS and GS1011MExS are complete 802.11b low power consumption Wi-Fi connectivity solutions.
The GS1011MIxS provides low power Wi-Fi connectivity with +9dBm of transmit output power, while the GS1011MExS is an extended range solution offering best in class transmit power of +18dBm.

The GS1011MIxS and GS1011MExS offer easy system integration and minimal use of host resources. The modules provide both UART and SPI interfaces, making it possible to connect to any 8-32 bit microcontroller using simple AT commands. The modules are pre-loaded with serial to Wi-Fi firmware with complete Wi-Fi functionality including security, WPS and provisioning features running on the module as well as the networking stack, an embedded HTTP server with network configuration pages, and limited AP capability for ease of provisioning.

The modules feature built-in trace or external antenna options through a U.FL connector, an industrial operating temperature range from -40 to 85 degrees Celsius, and are certified or pre-certified for all major regulatory requirements including FCC, IC and ETSI.

The size-optimized GS1011MIxS and GS1011MExS are the newest additions to GainSpan’s portfolio of Wi-Fi modules which include the soldered down GS1500M (802.11b/g/n) and ultra-low power GS1011M (802.11b), as well as the connectorized GS1011MIC.
