RN-42 Bluetooth Module

RN-42 Bluetooth Module

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.

Features

• 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

Applications

• Remote control a robot via PC, cell phone, or another microcontroller
• Measurement and monitoring systems
• Industrial sensors and controls
• Cable replacement (wireless serial interface)

Notes:

• 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.
