original Arduino Nano microcontroller board

The Original Arduino Nano Microcontroller Board is a compact, breadboard-friendly development board designed for space-constrained electronics and embedded projects. Powered by the ATmega328P microcontroller, it delivers the same core functionality as the Arduino Uno in a much smaller form factor.

The board features 14 digital I/O pins (including 6 PWM outputs) and 8 analog input pins, along with a 16 MHz crystal oscillator, mini-USB interface, and ICSP header. It can be powered via USB, external 5V, or 7–12V through the VIN pin, offering flexibility for portable and standalone applications.

Fully compatible with the Arduino IDE and an extensive library ecosystem, the Arduino Nano supports a wide range of sensors, modules, motors, and displays. Its small size and reliable performance make it ideal for robotics, wearables, IoT prototypes, automation systems, and educational projects.
