RN-42 Bluetooth Module.RN-42 Bluetooth Module - back view.

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.
 

Key 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.
     

Application Ideas:

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

Details:

  • 2 x 7 dual row male header with 0.1" spacing.
  • Jumper selectable default baud rates: 9.6 or 115.2 Kbps.
  • Command-configurable baud rate from 1.2 to 921 Kbps.
  • Range: ~ 35 – 50 feet line of sight indoors*.
  • Voltage requirements: 5.0 VDC or 3.3 VDC.
  • Current requirements: ~5 mA sleep; ~15 mA idle; ~20 mA transmit; ~50 mA max.
  • Communication: 5 V/3.3 V asynchronous serial interface with RTS/CTS flow control from 1.2 – 921 Kbps.
  • Dimensions: 2.33” x 1.16” x 0.45”  in (59.18 x 29.46 x 11.43 mm).
  • Operating temp range: -40 to +185 °F (-40 to +85 °C).
     

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.
