The Arduino Nano V3.0 Development Board is a small, complete, and breadboard-friendly development board built around the Microchip ATmega328P 8-bit AVR microcontroller running at 16 MHz.
The Arduino Nano V3.0 Development Board is a small, complete, and breadboard-friendly development board built around the Microchip ATmega328P 8-bit AVR microcontroller running at 16 MHz. It delivers the exact same computing capabilities, pin mapping, and library compatibility as the standard Arduino Uno, but in a significantly smaller 45mm × 18mm form factor.
This clone version uses the reliable CH340 USB-to-UART bridge IC for seamless serial communication and code flashing via PC. Power can be supplied via the onboard USB port, an unregulated external DC source (6V to 12V on the VIN pin), or a regulated 5V supply. The board automatically selects the highest available voltage source.
Supplied with unsoldered 2.54mm pitch male header pins, this model gives makers complete freedom to customize connections—whether soldering straight/right-angle pin headers for breadboard prototyping or soldering wires directly to the board for slim, permanent enclosures. It is fully compatible with the Arduino IDE, support shields, expansion boards, and custom IoT systems.
