Roving's most popular Wi-Fi module, the RN131, 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 RN131 to run for years on two standard AAA batteries. Using only 35mA when awake and 4uA when asleep, this remarkable power efficiency makes possible a new class of internet-enabled products.
The RN131 incorporates a 2.4 GHz radio, processor, TCP/IP stack, real-time clock, crypto accelerator, power management, and analog sensor interfaces. This complete solution 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 RN131 is available in 2 temperature grades. The RN131G is rated for industrial operating temperatures (-40C to +85C). The RN131C has all the features and capabilities of the RN131G, but is rated for commercial temperature (0C to +70C). The RN-131C is the perfect choice for those looking for a complete, low power, lower cost Wi-Fi module.
For the developer, Roving offers an evaluation board based on the RN-131, the RN134. Additionally, both development kits, the RN134K and RN131GEVAL, are based on the RN134 and include everything a developer needs to begin prototyping and designing with the RN131 module.
