Guide to the Arduino Nano

Connecting the Arduino Nano 2.2 to a computer with a Mini-B USB cable. Note the blue power LED underneath the board.


To connect the Arduino Nano to your computer, you'll need a Mini-B USB cable. This also provides power to the board, as indicated by the blue LED (which is on the bottom of the Arduino Nano 2.x and the top of the Arduino Nano 3.0).

If you have an Arduino Nano 3.0, you'll need to select Arduino Duemilanove or Nano w/ ATmega328 from the Tools > Board menu. If you have an Arduino Nano 2.x, select Arduino Diecimila, Duemilanove, or Nano w/ ATmega168. Select the correct serial port selected from the Tools > Serial Port menu. Then simply press the upload button in the Arduino environment. The board will automatically reset and the sketch will be uploaded. If you have any problems, see the troubleshooting guide.

For more details on the Arduino Nano, see the hardware page.
