SR7232S/ 2T2R/ 2.4GHz AP/ PCIe

Line

The module SR7232S is a complete, small form factor 802.11 b/g/n Wi-Fi Solution optimized for low power, low-cost, and highly integrated AP and consumer electronic devices, the module integrates all Wi-Fi functionality in a package friendly to low-cost PCB design, requiring only a few external 3.3V and connection to antenna.

The module based on the single chip QCA9531 which integrates an 802.11n 2x2 MIMO MAC/BB/ radio with internal PA and LNA. It supports 802.11 n operations up to 150 Mbps for 20MHZ and 300 Mbps for 40MHZ, and 802.11b/g data rates.

The module support AP mode and client mode at the same time and include mass service application software to reduce there search and design work of customer.
