Description: This Class-1 Bluetooth Shield(RN41) made by rhydoLABZ simplifies the task of interfacing bluetooth with your Arduinos, Yes it is compatible with Arduino Due,which require 3V3 as interfacing voltage as well as other Arduino boards and its clones. It is based on Arduino R3 layout with additional pins. This board mates directly with all Arduinos and equips it with wireless communication capabilities using the Bluetooth module. This unit build with the Roving Network's RN41 Class-1 bluetooth module and this unit uses an improved command set.
The shield is provided with a DPDT sliding switch which helps bluetooth module to connect either PC via USB or UART Pins of Arduino microcontroller. This feature helps you to configure or test the bluetooth module before using it in your project.No need for separate bluetooth development. Power is taken from the 5V pin of the Arduino and regulated on-board to 3.3VDC before being supplied to the bluetooth module. The shield also takes care of level shifting (5V to 3V3) on the RXD & TXD pin of the Bluetooth module.There is another onboard option(Jumper Selectable)is provided which allows you to connect Bluetooth module to either Digital UART or Software UART pins of the Arduino.
The board is polpulated with 3 state bus driver for converting 5V signal to 3V3 instead of normall voltage divider resistor network. Since we used the buffer we can use this shield with 3V3 as well .The board also includes LEDs to indicate power,Status and Connect pins of the Bluetooth module. The Arduino's reset button is brought out on the shield, and a 12x11 grid of 0.1" pad holes are available for prototyping. The shield does come with headers installed, So no Soldering required at all , just plug and play :-)

Note 1: Unit comes with interfacing voltage selection jumper(J9) setted to 5v, for connecting with Arduino DUE and similar 3V3 voltage boards user has to change this to 3v3 .
Note 2: This is a single unit only. We recommend the purchase a USB dongle to interface to a computer if you do not already have access to a computer with Bluetooth connectivity.
