Arduino Nano Pinout Diagram and Specifications


Hi, in this article, we are going to see the pinout diagram of Arduino Nano. Also, we will see the pin description. Arduino is a compact microcontroller board and it can be easily placed in a breadboard. It is inbuilt with the ATmega328P microcontroller. The main difference between Arduino Nano and Arduino UNO is, Arduino UNO comes with a Plastic Dual Inline Package or PDIP whereas Arduino Nano comes with a plastic quad flat package or TQFP. Also, the Arduino Uno has 6 ADC parts while Arduino Nano has 8 ADC parts.
