Using the miniature Roving Network / Microchip RN42 Bluetooth 2 Module, this board lets you communicate wirelessly with your TinyDuino via a standard serial port from your computer using Bluetooth SPP (Serial Port Profile Mode). When attached to your TinyDuino, this works just like the USB TinyShield (without the cable). The Bluetooth software is completely contained in the module, so there is no extra programming required. Just connect your computer or phone to the module and you're good to go!
This TinyShield is great for short range communications (10 – 20 meters) between your PC / Phone and TinyDuino setup. The Bluetooth module can support data rates of up to 2.0Mbps over the air. Includes power supply and level shifters on the board, so you can run your TinyDuino from 3.3V – 5V.
Note: Apple iPhones / iPad users should use the Bluetooth Low Energy TinyShield (ST) instead due to Apple licensing restrictions.

TinyDuino Power Requirements
By default, the Bluetooth TinyShield will power up at 57600 baud, so the TinyDuino processor needs to be configured at this baud rate in order for communications to work. Note: Several Bluetooth TinyShields have accidentally been shipped with the resistor R4 included on the assembly - this will set the UART baud rate to 9600. Check to see if this is present if you are having issues, if so, you will need to set the UART baud rate of your TinyDuino processor to 9600 baud. You can also remove the resistor to return this to 57600 baud, or contact us at TinyCircuits and we can modify the unit for you.
