Using the miniature Roving Network / Microchip RN42 Bluetooth 2
Module, easily lets you communicate wirelessly with your TinyDuino via
a standard serial port from your computer using Bluetooth SPP (Serial
Port Profile Mode).

Once connected, this works just like you are connected using USB to
your TinyDuino, except now without the wire, since the entire
Bluetooth stack software is completely contained in the module, there
is no programming required.

This TinyShield is great for short range communications (10 - 20
meters) between your PC / Phone and the Bluetooth module and can
support high 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
Shield instead due to Apple licensing restrictions.
