RN41 Bluetooth Module

RN41 Bluetooth Module

Rs 2,000  / PieceGet Best Price
Frequency Range2.405-2.48
Pin Count35
Bluetooth CertificationSIG Certified
Current Consumption in Sleep Mode250 microAmpere
The RN41 Bluetooth Module is a small form factor, low power, simple to integrate Bluetooth radio for OEMs adding wireless capability to their products. The RN41 is perfect for battery-powered applications and by default is ready to use in the SPP (Serial Port Profile) configuration. It uses current only in a small amount in sleep mode while still being discoverable and connectable. Multiple low power modes available allow you to dial in the lowest power profile for your application. The RN41 supports multiple Bluetooth profiles, is fully certified, and is simple to design in, making it a complete embedded Bluetooth solution. The RN41 is also available without antenna (RN41N). This is useful when the application requires an external antenna. The RN41N is form, function, and pin compatible with the RN41.
