Description

The RN-174 evaluation board is a field-ready, Wi-Fi Alliance

certified, 802.11 b/g prototyping platform for the RN-171

module. The board has the flexibility to connect directly to

embedded processors via a standard RS-232 interface or

through the TTL UART interface. The RN-174 contains a

battery boost circuit, which makes it possible to power the

board using two AA batteries (the input voltage can go down to

down to 2.0 V DC when using the battery boost circuit). The

battery boost circuit makes the RN-174 perfect for battery-

powered applications such as sensors, data acquisition

systems, controllers, etc. The status LEDs and jumpers enable

rapid prototyping and integration into existing systems.

The RN-174 is based on the Roving Networks RN-171 module.

The RN-171 module incorporates a 2.4-GHz radio, processor,

full TCP/IP stack, real-time clock, and supports the FTP, DHCP,

DNS, and HTML client protocols. The RN-171 is the smallest,

lowest power 802.11 b/g module available. The module

supports ad hoc and infrastructure networking modes.

The analog sensor interface provides direct connections to send

temperature, acceleration, and other analog data without

requiring an external microprocessor. The RN-171 module is

programmed and controlled with a simple ASCII command

language. Once the configuration is set up, the module can

automatically scan to find an access point, associate,

authenticate, and connect over any Wi-Fi network. Additionally,

the module can automatically send data to a remote host and

go back to a low-power sleep state once the data transmission

completes.
