Microchip Technology RN171 Wireless LAN Modules & Eval Boards

RN171 802.11 b/g Wireless LAN Modules are complete, standalone TCP/IP wireless networking module. It incorporates a 2.4GHz radio, 32-bit SPARC processor, TCP/IP stack, real-time clock, crypto accelerator, power management, and analog sensor interfaces. With its small form factor and extremely low power consumption, the RN171 is perfect for mobile wireless applications such as asset monitoring, sensors, and portable battery-operated devices.

The module is preloaded with firmware to simplify integration and minimize application development. In the simplest configuration, the hardware only requires four connections (PWR, TX, RX, and GND) to create a wireless data connection. Additionally, the analog sensor inputs can connect to a variety of sensors such as temperature, audio, motion, and acceleration. The ability to go into deep sleep mode and automatically scan and associate to an access point when awake makes the RN171 suitable for roaming applications. The RN171 also includes a built-in HTML client to post serial UART data or sensor data to a web server automatically. Two evaluation boards are also available, the RN-171-EK and the RN-171-PICtail.
