The Roving Networks RN-171-XV-W (now known as the Microchip RN171XVW-I/RM) is able to be plugged into virtually any XBee interface or a Waspmote (see below) and is designed for those who want to migrate their existing 802.15.4 architecture to a standard TCP/IP-based platform without having to redesign existing hardware. In other words, a project that is designed for an XBee module can be switched over to a standard WiFi network simply by dropping this module into the same socket.
The RN-XV module incorporates an 802.11b/g radio, a 32-bit processor, a TCP/IP stack, real-time clock, crypto accelerator, power management unit and analog sensor interface. The module is pre-loaded with firmware to simplify integration and minimize development time of your application. In the simplest configuration, the hardware only requires four connections (PWR, TX, RX and GND) to create a wireless data connection.

Can be used with Arduino This module is supported by the Arduino Communication Shield and many other Arduino shields that have an XBee socket.
Can be used with Raspberry Pi This module is supported by the Raspberry Pi to Arduino Connection Bridge.
Compatible with Waspmote A specific API has been developed to allow use of this module with a Waspmote sensor platform (this module plugs into Radio Socket 0 on your Waspmote main board, or into the Waspmote Expansion Board).
