RN-171-XV-DS RN-171-XV 802.11 b/g Wireless LAN Module Features Drop-in Wi-Fi solution for existing systems that currently use 802.15.4 modules Based on Roving Networks robust RN-171 Wi-Fi module Based on a pseudo-standard footprint On-board TCP/IP stack provides Internet access to every node No custom profiles needed Ultra-low power: 4-uA sleep, 40-mA Rx, 180-mA Tx at 10 dBm Configurable transmit power: 0 to +12 dBm Hardware interface: TTL UART Description Data rate: 464 Kbps using hardware flow control The RN-171-XV is a 802.11 b/g solution especially Through-hole board simplifies system integration designed for designers who want to migrate their existing 8 general purpose digital I/O pins 802.15.4 architecture to a more standard TCP/IP-based 3 analog sensor interfaces platform without redesigning their existing hardware. Real-time clock for wakeup and time stamping Based on a pseudo standard footprint often found in Complete TCP/IP networking stack embedded applications, the Roving Networks Wi-Fi Alliance certified for WEP, WPA, and RN-171-XV module provides Wi-Fi connectivity using WPA2-PSK 802.11 b/g standards in legacy and existing designs that WPS mode for easy configuration may have been based upon the 802.15.4 standard. FCC/CE/ICS certified and RoHS compliant The RN-171-XV module is based on Roving Networks robust RN-171 Wi-Fi module and incorporates an 802.11 b/g radio, a 32-bit SPARC processor, a TCP/IP Applications stack, a real-time clock, a crypto accelerator, power Industrial metering management unit, and an analog sensor interface. HVAC control The module offers additional functionality through its on- Room temperature sensors board programmable GPIO pins (10) and ADCs (8). The Pump configuration and control ADCs provide 14-bit resolution while the GPIOs can be Telemetry configured to provide standard functionality or status PV/solar controllers signaling to a host microcontroller, reducing the need for serial polling between the Wi-Fi module and host Robotics microcontroller. The module is pre-loaded with firmware to simplify integration and minimize applications development time. In the simplest configuration, the hardware only requires four connections (PWR, TX, RX, and GND) to create a wireless data connection. www.rovingnetworks.com Version 1.04 10/29/2012 1 RN-171-XV-DS OVERVIEW Host data rates up to 460 Kbps over the UART Intelligent built-in power management with programmable wakeup events (timers and I/O) Real-time clock for time stamping, auto-sleep, and auto-wakeup modes Configuration over Wi-Fi or UART using simple ASCII commands Supports over the air firmware upgrade via FTP Secure Wi-Fi authentication via WEP, WPA-PSK (TKIP), and WPA2-PSK Built-in networking applications: DHCP, DNS, ARP, ICMP UDP, Telnet, FTP client, and HTML client Configurable transmit power of 0 to 12 dBm WPS mode for easy and secure wireless setup Built-in HTML web client to send GPIO, UART, and sensor data to remote web servers The modules size is: Size0.96 x 1.15 Weight5.5 g Tables 1 through 5 provide detailed specifications for the module.
