The RN-41 is perfiect for battery powered applications.  The RN-41 uses only 250uA in sleep mode while still being discoverable and connectable.  Multiple low power modes available to the user allow you to dial in the lowest power profile for your application.

The RN-41 supports multiple Bluetooth profiles, is simple to design in, and fully certified, making it a complete embedded Bluetooth solution.

With its high performance on-chip antenna and support for Bluetooth Enhanced Data Rate (EDR), the RN-41 delivers up to 3 Mbps data rate for distances to 100 meters.  The RN-41 is the perfect product for engineers adding Bluetooth capability to their product without  spending significant time and money to develop Bluetooth specific hardware and software.
