GainSpan GS1011MIP Low-Power Wi-Fi Module with Internal PA PCB Trace Antenna

The GS1011M family of fully certified modules offers a quick, easy, and cost-effective way for device and appliance 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 an 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, Ad-hoc as well as Wi-Fi Protected Setup (WPS), for ease of provisioning.
