Features of Arduino Nano

• A small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) or ATmega168 (Arduino Nano 2.x)
• The same functionality of the Arduino Duemilanove, but in a different package
• Does not have a DC power jack
• Works with a Mini-B USB cable instead of a standard one
• This Nano was designed and is being produced by Gravitech
• Powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27)
• Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode, digitalWrite, and digitalRead functions
• They operate at 5 volts
• Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms
