The Arduino Nano is a small, complete, breadboard-friendly board based on the ATmega328. This Nano comes without soldered headers (these are also not included). This sign uses the same chip as the UNO, but is in a different package. This board does not have a DC power jack, and is controlled with a Mini-USB cable.
CharacteristicsMicrocontroller | ATmega328P |

It concerns the
3rd revision(newest) with the following changes:
- Stronger RESET circuit.
- SDA and SCL pins added to the AREF pin and 2 new pins to the RESET pin, namely the IOREF pin, allowing shields to adapt to the voltage from the board. In the future, shields will be compatible with both the 5v and 3.3v versions. The 2nd pin is not connected and is reserved for future updates.
This arduino is a clone, which means that this board was not built in the original factory. The only difference between original and clones is that these Arduinos are cheaper. All components and circuits are otherwise identical.
