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. To program this board, you need to use the USB TinyShield Adapter Board.
This version of the TinyDuino Processor Board comes without battery options - the lightest and lowest cost option in the range!
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)
