2. Setup

2.1 Driver Installation

The Nano V3.0 board utilizes the CH340G chip for USB communication. Before connecting the board, ensure the appropriate CH340G drivers are installed on your computer. These drivers are typically available for Windows, macOS, and Linux operating systems and can be found through a quick online search for 'CH340G driver'.

2.2 Arduino IDE Setup

This board is compatible with the Arduino IDE. Follow these steps to configure the IDE:

1. Download and install the latest version of the Arduino IDE.
2. Open the Arduino IDE.
3. Go to Tools > Board > Arduino AVR Boards and select Arduino Nano.
4. Go to Tools > Processor and select ATmega328P (Old Bootloader) if you encounter upload issues, otherwise use ATmega328P.
5. Go to Tools > Port and select the serial port corresponding to your connected Nano board.

2.3 Connecting and Powering the Board

Connect the Nano V3.0 board to your computer using the provided USB C cable. The board can be powered via:

• USB C Connection: Provides 5V power and enables programming.
• Unregulated External Power Supply: 6-12V connected to the VIN pin.
• Regulated External Power Supply: 5V connected to the 5V pin.

The board automatically detects and switches to the power source with the higher potential.

3. Operating Instructions

3.1 Programming the Board

Once the Arduino IDE is set up and the board is connected, you can upload sketches (programs) to the Nano V3.0 board. Write your code in the IDE, then click the 'Upload' button. The TX and RX LEDs on the board will blink during the upload process.

3.2 Pin Overview

The Nano V3.0 board offers a variety of pins for interfacing with other components:

• Digital I/O Pins: 14 pins (D0-D13), 6 of which can be used as Pulse Width Modulation (PWM) outputs.
• Analog Input Pins: 6 pins (A0-A5).
• Power Pins: 5V, 3.3V, GND, VIN.
• Communication Interfaces: UART (RX/TX), I2C (A4/A5), SPI (D10-D13).

5. Maintenance

The AYWHP Nano V3.0 Board is a robust electronic component, but proper care ensures its longevity and reliable operation:

• Handle with Care: Avoid dropping the board or applying excessive force to its components.
• Static Discharge: Microcontrollers are sensitive to electrostatic discharge. Handle the board on an anti-static mat or by touching a grounded object first.
• Cleanliness: Keep the board free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning if necessary.
• Storage: Store the board in an anti-static bag in a dry environment when not in use.
• Power Supply: Always ensure the power supply voltage is within the recommended range (5V via USB C, 6-12V via VIN).

6. Troubleshooting

If you encounter issues with your AYWHP Nano V3.0 Board, consider the following troubleshooting steps:

• Board Not Recognized by Computer:
  • Ensure CH340G drivers are correctly installed.
  • 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.
  • Restart your computer.
• Upload Errors in Arduino IDE:
  • Verify that the correct board (Arduino Nano) and processor (ATmega328P or ATmega328P (Old Bootloader)) are selected under Tools.
  • Confirm the correct serial port is selected under Tools > Port.
  • Check for syntax errors in your code.
  • Ensure no other software is using the serial port.
• Digital or Analog Pins Not Functioning:
  • Double-check your wiring connections.
  • Ensure the pins are correctly defined and used in your sketch.
  • Verify that the board is receiving adequate power.
  • Test with a simple sketch (e.g., blinking an LED) to isolate the issue.
• Power LED (PWR) Not Lighting Up:
  • Check your USB C cable connection.
  • Verify your external power supply is providing the correct voltage and is properly connected.
