1. General Description
The module
ITM-AP04-V2 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 allWi-Fi functionality in a package friendly to low-cost PCB design, requiringonly a few external 3.3V power supply and connection to antenna.
The module based on the single chip AR9331 which integrates an 802.11n
1x1 MAC/BB/radio with internal PA and LNA. It supports 802.11n operationsup to 72 Mbps for 20 MHz and 150 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 designwork of customer.
