RN-42 Bluetooth ModuleThe 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 microcontrollersApplications 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.Specifications 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: approx. 35 - 50 feet line of sight indoors* Voltage requirements: 5.0 VDC or 3.3 VDC Current requirements (approx.): 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)Downloads & Resources RN-42 Bluetooth Module Documentation RN-42 Bluetooth Module Schematic RN-42 Bluetooth Module BASIC Stamp Code RN-42 Bluetooth Module Advanced Users Manual
