Input and OutputEach 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. You could download the driver of Nano V3.0 . ATTENTION: We dont have USB cables in this kit and you will need to buy a mini USB cable to use this NANO board. Package Include : 3 X Nano Board PCB Size: 18 x 45 mm Weight: 7 g. |
