RN171-I/RM Datasheet PDF - Microchip

●RN171-I/RM 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. It incorporates a 2.4GHz radio, 32bit 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.
