TinyDuino Processor Board

The TinyCircuits TinyDuino is an Arduino compatible board in an ultra compact package. Imagine the possibilities of having the full power of an Arduino Uno in a size less than a quarter! 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.

Includes:

• Atmega328P processor (same as is used on the Arduino Uno)
• Reset switch
• Status LED
• 8MHz ceramic resonator
• Optional battery connector for CR1612-CR1632 coin cell batteries
• 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)

• Arduino and LilyPad Compatible
• Expandable with Stackable TinyShield Boards
• Optional battery connector for CR1612-CR1632 coin cell batteries
• 0.1" spaced solder holes for external power source
• Robust Gold Finish - makes soldering easy and is non-corrosive
• Ultra compact size and weight (smaller than a US Quarter!)
• Square Version: 20mm x 20mm (.787 inches x .787 inches)
• Circular Version: 20mm (.787 inches) diameter
• Max Height (without battery holder): 2.9mm (0.12 inches)
• Max Height (with battery holder): 6.58mm (0.26 inches)
• Ultra-thin 0.61mm (0.024 inches) PCB
• Weight: TBD grams (TBD ounces)
• Atmel ATmega328P Microcontroller
• 32KB Flash, 2KB RAM, 1KB EEPROM
• 1.2mA (typical) @ 3V, 4MHz
• Default Clock speed: 8MHz
• 2.7V – 5.5V operating voltage (Arduino mode)
• 1.8V – 5.5V operating voltage (with custom fw)
• 20 I/Os (14 Digital, 6 Analog / Digital I/O) - All the signals on the Arduino Shield connectors are supported!
• Arduino Bootloader preprogrammed (uses approx 0.5 KBytes of Flash Memory)

• Schematic (pdf)

• Eagle Design Files (on GitHub)
