The module ComIoT-05 is a complete, small form factor 802.11 b/g/n Wi-Fi solution optimized for low-cost and highly integrated with high power for consumer electronic devices and products. The module integrated Wi-Fi functions in a single and small form factor which is friendly to low-cost PCB design that requiring only a few external 3.3V & 5V power supply and connection to antenna. The module based on the single chip QCA9531 which integrated with an 802.11n 2x2 MAC/BB/radio with external 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. The performance of the module allows to support multiple types of service application and software which can help to reduce a research and design work of a customer.
