Description
The RN-171 module is a complete, standalone TCP/IP
wireless networking module. With its small form factor
and extremely low power consumption, the RN-171 is
perfect for mobile wireless applications such as asset
monitoring, sensors, and portable battery operated
devices. It incorporates a 2.4-GHz radio, 32-bit SPARC
processor, TCP/IP stack, real-time clock, crypto
accelerator, power management, and analog sensor
interfaces.
The module is preloaded with firmware to simplify
integration and minimize application development. In
the simplest configuration, the hardware only requires
four connections (PWR, TX, RX, and GND) to create a
wireless data connection. Additionally, the analog sensor
inputs can connect to a variety of sensors such as
temperature, audio, motion, and acceleration. The ability
to go into deep sleep mode and automatically scan and
associate to an access point when awake makes the
RN-171 suitable for roaming applications. The RN-171
also includes a built-in HTML client to post serial UART
data or sensor data to a web server automatically.
