Low-cost 19.4x28.7mm Wi-Fi modules target the Internet of Things

May 09, 2012 // By Julien Happich
Extending its portfolio of embedded Wi-Fi modules, Alpha Micro Components introduced the Gainspan GS1011MIPS and GS1011MExS, two of the smallest modules on the market.

At just 19.4x28.7mm, the new modules provide a significant reduction in footprint and offer an easy to integrate, compact and cost-effective solution for any power critical cost sensitive wireless application in the emerging Internet of Things arena. Despite the small form factor, the GS1011MIPS and GS1011MExS offer complete 802.11b ultra low power Wi-Fi client or AP solutions. The GS1011MIPS provides low power Wi-Fi connectivity with +8dBm of transmit output power, while the GS1011MExS is an extended range solution offering best in class transmit power of +18dBm. Both units 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 8/16/32 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.
