Arduino nano: Learn everything about Arduino

Learn everything about Arduino Nano – its features, pinout diagram, beginner-friendly projects, and why it's perfect for electronics and IoT enthusiasts. Nano The Arduino Nano is Arduino 's classic breadboard friendly designed board with the smallest dimensions. The Arduino Nano comes with pin headers that allow for an easy attachment onto a breadboard and features a Mini-B USB connector. The Arduino Nano is programmed by Arduino Software called IDE which is a common software used for almost all types of board available. Simply download the software and select the board you are using. The Arduino Nano is a small breadboard-friendly microcontroller board based on the ATmega328 MCU. It has more or less the same functionality of the Arduino Uno R3, but in a smaller package of 45mm x 18mm (1.77in x 0.71in) with the DC power jack and USB Type-B female connector replaced by a single Mini-B USB connector for both power and data. This hardware overview Arduino Nano board covers specs, board layout, pinout, power, I/O, and accessories.
