4. Setup
To begin using your AYWHP Nano V3.0 board, follow these steps:
- Install USB Chip Driver: The Nano V3.0 board uses the CH340G USB-to-serial converter chip. You may need to download and install the appropriate CH340G driver for your operating system (Windows, Mac, Linux). In many cases, the driver will install automatically upon first connection. Search online for "CH340G driver" if automatic installation fails.
- Connect the Board: Plug the Nano V3.0 board into your computer using the provided USB-C cable.
- Open Arduino IDE: Launch the Arduino Integrated Development Environment (IDE). If you don't have it, download it from the official Arduino website.
- Select Board: In the Arduino IDE, navigate to Tools > Board and select "Arduino Nano".
- Select Processor: Under Tools > Processor, select "ATmega328P (Old Bootloader)" or "ATmega328P" depending on your specific board's bootloader version. If you encounter upload errors, try the other option.
- Select COM Port: Go to Tools > Port and select the COM port corresponding to your connected Nano V3.0 board. This port will typically appear after the CH340G driver is successfully installed.
- Upload a Test Sketch: Open a simple example sketch, such as File > Examples > 01.Basics > Blink. Upload this sketch to your board to verify proper setup. The onboard LED should start blinking.

5. Operating Instructions
Once your Nano V3.0 board is set up, you can begin programming and interacting with it.
5.1 Powering the Board
- USB-C: Connect the board to your computer via the USB-C cable. This provides both power and data communication.
- External Unregulated Power: Connect a 6-12V DC power supply to the VIN pin.
- External Regulated Power: Connect a 5V DC power supply to the 5V pin.
The board automatically switches to the power source with the highest voltage potential.
5.2 Programming the Board
Use the Arduino IDE to write and upload your sketches (programs) to the Nano V3.0 board. Ensure the correct board and port are selected as described in the Setup section.
5.3 Using I/O Pins
- Digital Pins (D0-D13): Can be configured as inputs or outputs using
pinMode(),digitalWrite(), anddigitalRead()functions. - PWM Pins: Pins D3, D5, D6, D9, D10, D11 support Pulse Width Modulation (PWM) for analog-like output using
analogWrite(). - Analog Input Pins (A0-A5): Used to read analog sensor values using
analogRead().

6. Maintenance
Proper care and maintenance will extend the lifespan of your Nano V3.0 board.
- Handling: Always handle the board by its edges to avoid touching components, especially the pins, which can be sensitive to static electricity.
- Storage: Store the board in an anti-static bag or container when not in use, away from dust, moisture, and extreme temperatures.
- Cleaning: If necessary, gently clean the board with a soft, dry brush or compressed air to remove dust. Avoid using liquids or abrasive materials.
- Power Supply: Ensure that the power supply voltage and current are within the specified limits to prevent damage to the board.
7. Troubleshooting
If you encounter issues with your Nano V3.0 board, consider the following troubleshooting steps:
- Board Not Recognized:
- Verify that the CH340G driver is correctly installed. Check your computer's Device Manager (Windows) or System Information (Mac) for the USB-SERIAL CH340 device.
- Try a different USB-C cable. Some cables are for charging only and do not support data transfer.
- Test with a different USB port on your computer.
- Upload Errors:
- Ensure the correct board (Arduino Nano) and processor (ATmega328P or ATmega328P (Old Bootloader)) are selected in the Arduino IDE.
- Confirm that the correct COM port is selected.
- Check for syntax errors in your code.
- Press the reset button on the Nano board just before or during the upload process if uploads consistently fail.
- Power Issues:
- If using external power, ensure the voltage is within the 6-12V range for VIN or exactly 5V for the 5V pin.
- Check all power connections for proper polarity and secure contact.
- Component Malfunction: If individual components or pins are not responding, carefully inspect for any visible damage, solder bridges, or cold solder joints.
For further assistance, consult online Arduino communities and forums, which often have solutions for common issues.
