Description
The RN-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-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-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.
