Introduction
The module YH-IOT05 is a complete, small form factor 802.11 b/g/n Wi-Fi Solution.
optimized for low-cost, and highly integrated ,high power consumer electronic devices, the module integrates all WiFi
functionality in a package friendly to low-cost PCB design, requiring only a few external 3.3V and 5V power supply and
connection to antenna.
The module based on the single chip QCA9531 which integrates an 802.11n 2x2 MAC/BB/radio with internal PA and
LNA. It supports 802.11n operations up to 144 Mbps for 20 MHz and 300 Mbps for 40 MHz channel respectively, and
IEEE 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
the research and design work of customer.The general Hardware architecture is shown below Figure:
