Overview

The Arduino Nano V3 (A000005) is a compact, breadboard-friendly development board based on the AVR ATmega328P microcontroller. It provides a USB-to-serial interface for programming and serial I/O and exposes the Arduino-compatible pinout in a small form factor. The board is intended for quick prototyping, embedded learning, and small-scale projects.

Why Choose This Part

The Nano V3 is very compact and breadboard-friendly, making it easy to integrate into prototypes and small enclosures. It benefits from the large Arduino ecosystem: extensive libraries, community examples, and wide compatibility with shields and sensors. Its USB-to-serial interface simplifies programming and serial debugging.

Applications

Breadboard prototyping
Use as a compact controller when building circuits on a breadboard or perf board.
USB serial sensor nodes
Collect sensor data and stream logs to a PC or attached USB host for debugging and data capture.
Small robotics and actuator control
Control servos, motors, and simple robot behaviors where a compact 8-bit MCU is sufficient.
Education and firmware learning
Learn embedded C/C++ and Arduino APIs with a widely used, well-documented board.
Bootloader-based firmware updates
Deploy and update firmware via USB without a separate ISP programmer.

Getting Started

Install the Arduino IDE (or an alternative like PlatformIO), connect the Nano to your PC via USB, and select the "Arduino Nano" board profile in the IDE. You may need to install a USB driver depending on the USB-serial chip used (official Nanos use FTDI; many clones use CH340). Upload sketches using the IDE; for some boards you must choose the correct processor/bootloader variant in the board menu.
