DESCRIPTION
**As an alternative to the RN174, we recommend the RN-171-EK kit for evaluating the RN171 module.**
The RN174 prototyping board is a Wi-Fi certified 802.11 b/g solution. It 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 integration into existing systems.
The RN174 is built upon Roving Networks RN171 module. The RN171 module incorporates a 2.4 GHz radio, processor, full TCP/IP stack, real-time clock, FTP, DHCP, DNS, and HTML client to connect to a remote server. The RN171 is the smallest, lowest power 802.11 b/g module available. The module supports ad hoc and infrastructure networking modes.
In the simplest configuration the hardware only requires four connections (PWR, TX, RX, GND). Additionally, the analog sensor interface provides direct connections to send temperature, acceleration, and other analog data without requiring additional hardware. The RN171 is programmed and controlled with simple ASCII command language. Once the RN171 is set up it can scan to find an access point, associate, authenticate, and connect over any Wi-Fi network.
The RN174 is available in multiple antenna configurations such as Wire, chip, U.Fl connector and a SMA connector.
