Introduction

The RN171 is a standalone, embedded 802.11 b/g Wireless Local Area Network (WLAN) module. The module incorporates an on-board TCP/IP networking stack, cryptographic accelerator, power management subsystem, real-time clock, versatile sensor interface, 2.4 GHz transceiver, and RF power amplifier. With the RN171, designers can embed Wi-Fi and networking functionality rapidly into virtually any device. The RN171 provides cost and time-to-market savings as a self-contained internet-enabling solution. The module has been designed to provide designers with a simple Wi-Fi solution that features ease of integration and programming, vastly reduced development time, minimum system cost, long battery life, and maximum value in a range of applications. The RN171 is configured with a simple ASCII command language. In the simplest configuration, the module requires only power, ground, and UART TX and RX connections. The RN171 module can interface to low-cost microcontrollers using only two wires, UART TX and RX. The RN171 has a versatile sensor interface that can be used to monitor analog signals such as temperature, audio, motion, and acceleration. The module has a small form factor, which makes it easy to integrate. Additionally, the module is compatible with standard pick-and-place equipment. The RN171 is ideal for a vast range of applications that require long battery life, moderate processing power, moderate data throughput and occasional Wi-Fi connectivity.
