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)

NOTES
- If you are brand new to the TinyDuino, buying a kit is the best way to go since it will have all the parts needed. Check out the TinyDuino Kits here
- All batteries are sold separately
-
To program this board, you need to use the USB TinyShield Adapter Board, which is sold separately.

It actually plays my old home videos on a screen the size of a stamp. It's my desk's favorite object.
The remote is absurd and I love it. Setup took five minutes and my clips looked crisp on that little screen.
Build quality is unreal for something this small. Feels like a real gadget, not a toy — and it's made here.
Gifted one to my brother and now the whole family wants one. Tiny, but seriously mighty.
Battery lasts through a work day on my shelf and the fireplace loop is weirdly cozy. Zero regrets.
Loading my own videos over USB was dead simple. It's the best desk conversation-starter I own.
