The Arduino Nano is a small yet powerful development board built around the ATmega328P microcontroller. Despite its compact size, it offers the same core functionality as the Arduino Uno, making it perfect for projects where space matters. It is fully compatible with the Arduino IDE and supported by the massive open-source ecosystem from Arduino. The Nano is breadboard-friendly and commonly used in wearables, robotics, sensors, and DIY electronics. If you need Uno-level capability without the bulk, this is the board to use.
