RN-171 802.11 b/g Wireless LAN Module
Due to its small form factor and extremely low power consumption, it is perfect for mobile wireless applications such as asset monitoring, sensors, and portable battery operated devices. For quickly and easily evaluating the RN171 module, Microchip offers the RN-171-EK, a compact, battery and USB-powered kit with pushbuttons for AP and WPS mode.
For the developer, Roving offers an evaluation kit based on the RN171, the RN-171-EK. This easy-to-use kit quickly adds Wi-Fi connectivity to embedded applications. It has the flexibility to connect directly to a PC via a standard USB interface or to embedded processors through the TTL/UART interface. The board includes 2 convenient pushbuttons for controlling both SoftAP and WPS (Wi-Fi Protected Setup) mode without software configuration. The status LEDs and jumpers enable rapid prototyping and integration into existing systems.
