The Arduino Nano 3.0 is a surface mount breadboard compatible version of the ever-popular Arduino micro controller. It’s small, has integrated USB, and is breadboard friendly. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. Physically, it’s missing the power jack, but it can still sense and switch to the higher potential source of power. It’s perfect for embedding into your next project.
