RN-171 Wireless Network Module

Roving Networks' RN-171 module is a standalone complete TCP/IP wireless networking module. Due to its small form factor and extremely low power consumption, the RN-171 is perfect for mobile wireless applications such as asset monitoring, sensors and portable battery operated devices. It incorporates a 2.4 GHz radio, 32 bit SPARC processor, TCP/IP stack, real-time clock, crypto accelerator, power management and analog sensor interfaces. This module is preloaded with firmware to simplify integration and minimizes development of an application. 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 be used to interface 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 AP when awake makes the RN-171 suitable for roaming applications. The RN-171 also includes a built in HTML client to automatically post serial UART data or sensor data to a web server.
