Arduino Nano V3.0

Nowadays the electronic devices are becoming compact, flexible, and cheap that are capable of doing more function as compared to their predecessors. A Microcontroller was introduced as a new innovation in the electronics industry. Designed with the purpose of making our tasks easier, with minimum effort, and gives maximum output. Arduino Nano version 3 is an open-source small embedded development board based on the Microchip ATmega328 SMD package developed by Arduino. cc. Meanwhile, the current version of Arduino Nano comes with a mini USB port.

The current version of Arduino Nano comes with 14 digital I/O pins, 8 analogue pins, an ICSP header, 16 MHz ceramic resonators. And an Atmega328 microcontroller is used to connect with external electronics circuits. Out of 14 I/O ports, 6 pins were used for PWM output. This Arduino board lacks a DC power jack. Each pin operates at a voltage of 5V providing a maximum of 40mA. It also supports serial communication using Tx and Rx pins. As the DC Power Jack is not available on this Board, power can be given through Mini USB Cable.

This Arduino Nano board automatically senses and switch to the higher potential source of power. As a result, there is no need for a power select jumper. Moreover, this microcontroller is programmable with the Arduino IDE common to all our boards. The Arduino Nano is powered via a Mini-B USB, 6-20V unregulated external power supply, or 5V regulated external power supply.
