RN-XV Wifly XBee (RN-171 XV, Wire antenna)
RN-XV XBEE The RN-171-XV is a 802.11 b/g solution especially designed for designers who want to migrate their existing 802.15.4 architecture to a more standard TCP/IP-based platform without redesigning their existing hardware.
Based on a pseudo standard footprint often found in embedded applications, the Roving Networks’ RN-171-XV module provides Wi-Fi connectivity using 802.11 b/g standards in legacy and existing designs that may have been based upon the 802.15.4 standard.
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 stack, a real-time clock, a crypto accelerator, power management unit, and an analog sensor interface.
The module offers additional functionality through its on- board programmable GPIO pins (10) and ADCs (8). The ADCs provide 14-bit resolution while the GPIOs can be configured to provide standard functionality or status signaling to a host microcontroller, reducing the need for serial polling between the Wi-Fi module and host 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.
