The Roving Networks RN-134 “SuRF” board is a field ready, WiFi certified 802.11 b/g solution. The SuRF board has the flexibility to connect directly to a standard RS232 interface or through the TTL UART interface to embedded systems. The status LEDs and jumpers enable rapid prototyping and integrating into existing systems.

The RN-134 is built upon Roving Networks RN-131 WiFly-GSX module. The WiFly GSX module incorporates a 2.4GHz radio, processor, Full TCP/IP stack, real-time clock, FTP, DHCP, DNS and web server. The RN-131G is the smallest, lowest power 802.11 b/g module available . The module supports adhoc and enterprise networking modes.
