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.
