TinyLily Mini measures less than a U.S. dime, just 14 mm (0.55 inches) in diameter
TinyDuino supports TinyShields – small, stackable boards which contain modules such as Bluetooth and WiFi
TinyDuino is smaller than a U.S. quarter, measuring 20 x 20 mm (0.78 x 0.78 inches)
The TinyShield interface supports all the signals that are supported on standard Arduino Shield connectors
TinyDuino boards can be plugged into a computer and programmed with the Arduino IDE
Both the TinyDuino and TinyLily Mini are significantly smaller than, but compatible with, existing Arduino models
The popular open-source Arduino microcontroller has been implemented in countless projects worldwide, and this very success has led the hacker community to create several smaller and cheaper alternatives to the Arduino, such as the Digispark. TinyDuino continues in this miniaturization trend but, crucially, does so while promising to retain all the flexibility of its illustrious forbear.
