The GS1011MxxS family of size-optimized, fully certified modules offers a quick, easy and cost effective way for device and appliance manufacturers to add Wi-Fi capabilities to their products, while offering a smaller footprint for space constrained application boards. The module dimensions are 28.7mm * 19.4mm, resulting in board area savings of approximately 34% when compared to the GS1011MEx modules. The GS1011MxxS modules provide multiple serial UART or SPI interfaces, enabling connection to embedded designs utilizing an 8/16/32-bit microcontroller, via simple commands. These are lower pin-count modules (36 pins) compared to full-featured GS1011Mxx modules (48 pins). The GS1011MxxS 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/g/n wireless networks 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.
