The RN-42 Bluetooth Module provides a reliable method for creating a wireless serial communication interface between two devices such as a microcontroller, PC, cell phone, or another module. This module can pair up with devices supporting Bluetooth SPP (Serial Port Profile) to establish a serial interface. The RN-42 Bluetooth Module is breadboard-friendly and is compatible with all 5 V and 3.3 V microcontroller platforms.
- Fully qualified Bluetooth 2.1/2.0/1.2/1.1 module provides compatibility with many devices
- Low power consumption for long-lasting battery-powered projects
- Auto-connect/discovery/pairing modes make connecting to other modules easy
- LED indicators provide visual status of connection/mode
- Voltage jumper selects for use with 5 V and 3.3 V microcontrollers
- Remote control a robot via PC, cell phone, or another microcontroller
- Measurement and monitoring systems
- Industrial sensors and controls
- Cable replacement (wireless serial interface)
- This device supports Bluetooth Serial Port Profile (SPP). When connecting to another device please be sure your device supports SPP as well.
- *Operating throughput and range may vary depending on environmental circumstances and RF interference.
- Please note that this product is not backwards compatible with the retired Easy Bluetooth module.
