Joy-IT NanoV4MC3V Arduino Nano Compatible Board with ATmega328P Microcontroller

Prototyping with microcontrollers often means choosing between cost, compatibility, and reliability. The Joy-IT NanoV4MC3V solves this by delivering an Arduino Nano-compatible board built around the trusted ATmega328P, so you can run existing sketches without modification. Its compact footprint and CH340 USB-serial interface make it ideal for breadboard projects, wearable electronics, and embedded systems where space is tight.

Who is it for

This board is for makers, students, and engineers who need a low-cost, breadboard-friendly Arduino solution. It suits anyone migrating from an original Arduino Nano or building projects that require a small, 5V logic microcontroller with plenty of community support.

Main features

Tips

When using the CH340 chip, install the appropriate driver for your operating system before uploading sketches. For battery-powered projects, keep the input voltage between 7 V and 12 V to avoid overheating the onboard regulator. The board's pinout matches the original Arduino Nano, so most shields and tutorials will work without changes.
