Product description

Input and Output

Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. Some pins have specialized functions:
Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the CH340G USB chip.

The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Nano 3.x). It has more or less the same functionality of the official UNO, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
