The TinyCircuits TinyDuino is an Arduino compatible board in an ultra compact package. The TinyDuino processor board is roughly equivalent to the Arduino Uno board – same processor, same signals brought out to a shield connector. In fact, most Arduino sketches will work as is without any changes.
The TinyDuino Processor Board is available in three variations:
With Lithium Battery Support - has an on-board Lithium battery charger that will charge the battery when attached to USB
With coin cell battery support - for low power applications, use a simple CR1632 coin cell battery that can be easily changed
Without battery options - the lightest and lowest cost option
Main Features:
Atmega328P processor (same as is used on the Arduino Uno)
Power Switch
Status LED
8MHz ceramic resonator
External power supported with a 0.1″ power connection holes
Supports automatic switching between +5V and VBATT (if +5V is present, it will be used instead of the battery)

This board does not include a voltage regulator – do not supply more than +5.5V to VBATT or the +5V signal or you will permanently damage the board and ruin your day.
