TinyDuino Processor Board
DESCRIPTION
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.
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)

Customer Reviews
I have purchased many of these Tinyduino Processors. I never had a problem with any of them, even in an outdoor environment. They are powerful, fast, and small size that fits every space. These are perfect for my needs. They do just about everything.
Works like a charm.
Very powerful for its size, does everything I have need for. I'm quite satisfied.
Word great!
Very well made and reliable. We have been using TinyCircuits products for years and are very satisfied with the results.
The TinyArduino is compact, easy to program and
comes with a battery power supply.
Told it was an old model after I bought it and it never worked!
