The RN-XVee module supports infrastructure networking for worldwide
internet access directly by every node and AdHoc connectivity for fully
connected point to point networks, unlike many 802.15.4 implementa-
tions that need extensive, custom network application proles and ad-
ditional bridging products. The RN-XVee supports industrial temperature
ranges, making it ideal for applications such as sensor networks, industrial
or commercial controllers, utility meters and M2M applications.
The RN-XVee module is built upon Roving’s RN-171 ultra-low power
802.11 b/g technology, which boasts a complete onboard TCP/IP stack
with a simple UART or SPI slave HW interface. The stack offers network
services including IPv4 addressing with full WEP/WPA/WPA2 security,
FTP/HTTP client, UDP, TCP, HTTP, Telnet, DNS, and DHCP and
Wi-Fi protected setup (WPS) amongst others.
In sleep mode the module consumes as little as 4µA but can wake,
associate, and send a full network packet in less than 100ms. In the con-
nected state the module consumes only 35mA and its congurable output
power allows for an optimized TX power consumption. The RN-XVee pins
can be congured for digital GPIO or analog inputs. The analog inputs
provide 14-bit A to D converter resolution while the GPIO can be cong-
ured to signal a host microcontroller to simplify the interface between the
Wi-Fi module and host controller and further reduce system wake times.
The module complete with onboard stack is available in low quantities for
only $34.95 USD and is offered with step pricing for volume orders.
