Low cost, HF-A11, WiFi module

Ethernet, UART supported and High Performance

The cost effective HF-A11 Embedded WiFi Module provides 802.11b/g/n 2.4 GHz WiFi networking for a PCB device design. HF-A11 is a high performance feature rich embedded module and is available in a through hole pin header and surface mount version. Both mounting versions of the HF-A11 have the option of either an internal chip antenna or an U.FL / IPEX external antenna connection. The pin header version of the HF-A11 is also available with an SMA coaxial RF connector. (Please check with us if you would like to use SMA RF connector version.)

HF-A11 provided with 10/100 Ethernet and high speed UART interfaces available to be configure the device with a user-friendly web page or via an AT+ instruction set.

HF-A11 can operate in Infrastructure Station (STA) mode, Soft Access Point (AP) mode or AP+STA mode. Support for Router/Bridge mode networking is also provided.

With an industrial temperature range the HF-A11 can be used in devices designed for harsh environments. Multiple mounting and antenna options allow the HF-A11 to be added to existing device designs or to provide engineers with the design flexibility to meet exacting requirements. The HF-A11 is a member of a complete line of Embedded WiFi Modules provided by Elecom Electronics Supply. Need a smaller device size, lower power, SPI interface or USB? Elecom Electronics Supply can help pick the best WiFi embedded module to meet your needs.

With a small footprint, low cost, and rich feature set the HF-A11 Embedded WiFi Module is well suited for many applications, like Handheld devices, tablet...etc
