Details Information


Fn-Link Technology would like to announce a low-cost and low-power consumption module which has all of the Wi-Fi and Bluetooth functionalities. The highly integrated module makes the possibilities of web browsing, VoIP, Bluetooth headsets applications. With seamless roaming capabilities and advanced security, also could interact with different vendors’ 802.11a/b/g/n/ac 2x2 Access Points in the wireless LAN. 

5263B-SS module complies with IEEE 802.11 a/b/g/n/ac 2x2 dual-band Wi-Fi subsystem and a Bluetooth subsystem. The Wi-Fi subsystem contains the 802.11 a/b/g/n/ac radio, baseband, and MAC that are designed to meet both the low power and high throughput application. 

5263B-SS has a 32-bit RISC MCU that handles Wi-Fi and Bluetooth tasks,and could offload data frame processing in Wi-Fi host driver.The Bluetooth subsystem contains the Bluetooth radio, baseband, link controller. 

This compact module is a total solution for a combination of Wi-Fi and Bluetooth V5.0 technologies. The module is specifically developed for all portable devices.
