Introduction

The RN-131 module is a standalone, embedded wireless 802.11 b/g networking module. With its small form factor and extremely low power consumption, the RN-131 is perfect for mobile wireless applications such as asset monitoring, GPS tracking, and battery sensors. The WiFly module incorporates a 2.4-GHz radio, processor, TCP/IP stack, real-time clock, crypto accelerator, power management, and analog sensor interfaces. The module is preloaded with software to simplify integration and minimize application development. In the simplest configuration, the hardware requires only four connections (PWR, TX, RX, and GND) to create a wireless data connection. Additionally, the sensor interface provides temperature, audio, motion, acceleration, and other analog data without requiring additional hardware. The module is programmed and controlled with a simple ASCII command language. Once the module is set up, it can scan to find an access point, associate, authenticate, and connect over any Wi-Fi network.
