The Arduino Nano is a compact, breadboard-friendly microcontroller development board based on the ATmega328P. It offers the same core functionality as the Arduino Uno in a much smaller form factor, making it ideal for space-constrained embedded projects.
With 22 I/O pins, 8 analog inputs, and support for SPI, IC, and UART communication, the Arduino Nano is widely used in prototyping, robotics, automation, wearable electronics, and educational projects. It is fully compatible with the Arduino IDE and supports programming via Mini-USB.
