Microchip RN41 Bluetooth Module RN41SM-I/RM

RN-41-SM Bluetooth 2.1 + EDR Class 1 Socket Module

The RN41-SM is a through-hole PCB module featuring the RN41 Bluetooth Class 1 radio designed 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 only 250μA 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.
