DESCRIPTION
The RN131C is a complete, ultra-low power embedded TCP/IP solution.
The combination of ultra-low power and the ability to wake up, connect to a wireless network, send data, and return to sleep mode in less than 100 milliseconds, allows the RN131C to run for years on two standard AAA batteries. Using only 35mA when awake and 4µA when asleep, this remarkable power efficiency makes possible a new class of internet-enabled products.
The RN131C is a complete solution as it incorporates a 2.4 GHz radio, processor, TCP/IP stack, real-time clock, crypto accelerator, power management, and analog sensor interfaces. The module is pre-loaded with software to simplify integration and minimize development time for applications. In the simplest configuration, the hardware only requires four connections (PWR, TX, RX, GND) to create a wireless data connection.
The RN131C has all the features and capabilities of the RN131G, but is rated for commercial temperature (0C to +70C).
For the developer, Roving offers an evaluation board based on the RN131, the RN-131-EK. This easy-to-use kit quickly adds Wi-Fi connectivity to embedded applications. For those using the Microchip development ecosystem, the RN-131-PICtail works seamlessly with Microchip's PIC18 Explorer and Explorer 16 development boards. The RN-131-PICtail plugs into the PICtail™ modular connector on the PIC18 Explorer Board and the PICtail Plus connector on the Explorer 16, adding wireless functionality to the microcontroller.
