Electronics for IoT, Prototyping & DIY

This compact Nano V3.0 compatible ATmega328P micro-controller board is fully compatible with Arduino Nano and delivers the same functionality as larger Arduino boards in a breadboard-friendly package. It features the CH340G USB-to-serial chip for reliable programming via Mini-B USB, 14 digital I/O pins (6 PWM), 8 analog inputs, and runs at 16 MHz with a pre-installed bootloader -- ready to program with the Arduino IDE right out of the box.

💡 Tip: This board uses the CH340G USB chip, which may require a one-time driver installation on your computer before the Arduino IDE can detect it. Driver downloads are available for Windows, macOS, and Linux. 📦 Available Variations

Solderless Breadboard -- For prototyping circuits
Jumper Wires -- For connecting components to the board

🔧 How It Works

Install the CH340G USB driver on your computer (Windows, macOS, or Linux)
Download and install the Arduino IDE
If you have the Loose Pins version, solder the header pins onto the board first
Plug the board into a breadboard and connect to your computer with a Mini-B USB cable
In the Arduino IDE, select Tools > Board > Arduino Nano and Tools > Processor > ATmega328P
Select the correct COM port under Tools > Port
Upload your sketch and start building!

💡 Tip: If uploading fails with an avrdude: stk500_getsync() error, try changing the processor to ATmega328P (Old Bootloader) under Tools > Processor. Some boards ship with the older bootloader version.

See our User Guide for detailed Pinout, CH340G Driver Installation Instructions, Wiring, Example Sketches & Troubleshooting.

🔌 Compatible With

Arduino IDE (select board: \"Arduino Nano\", processor: \"ATmega328P\")
Arduino Nano shields and expansion boards
Standard solderless breadboards
All Arduino libraries compatible with ATmega328P
PlatformIO and other AVR development environments
Windows, macOS, and Linux (with CH340G driver)

🎯 Typical Applications

Learning programming and electronics fundamentals
Sensor monitoring (temperature, humidity, light, motion)
Home automation and relay control
Robotics and motor control (servos, steppers, DC motors)
IoT prototyping with Wi-Fi/Bluetooth modules (ESP8266, HC-05)
Data logging and serial communication projects
Wearable and portable electronics

⚠️ Important Notes

Do not exceed 20 mA per I/O pin or 200 mA total across all I/O pins
The 3.3V pin supplies a maximum of 50 mA -- do not use it for high-current 3.3V devices
When using VIN, keep input between 7–12V. Voltages above 12V may cause the regulator to overheat
Pins D0 (RX) and D1 (TX) are shared with USB serial -- avoid using them during serial communication
Pins A6 and A7 are analog input only and cannot be used as digital I/O
This board is compatible with Arduino Nano but is not manufactured by or affiliated with Arduino
