Setup Guide
- Power Connection: Connect the ESP32 development board to your computer using the provided Micro-USB cable. This will power the board and establish a serial communication link.
- Driver Installation: Depending on your operating system, you may need to install USB-to-serial drivers (e.g., CP210x or CH340G drivers) for your computer to recognize the board. Refer to online resources for specific driver installation instructions.
- Development Environment Setup: Install a suitable Integrated Development Environment (IDE) such as Arduino IDE or PlatformIO. Configure the IDE to support ESP32 boards.
- First Program Upload: Once the IDE is set up, you can upload your first program (sketch) to the board. Ensure the correct board type and COM port are selected in your IDE. The board supports automatic download.
- TF Card Insertion (Optional): If your application requires external storage, insert a formatted TF card (up to 4GB) into the designated slot on the board.

Maintenance and Care
- Handling: Handle the board by its edges to avoid touching components, especially the screen and exposed circuitry, which can be sensitive to static electricity.
- Cleaning: Use a soft, dry, lint-free cloth to gently wipe the screen and board. Avoid using liquid cleaners or abrasive materials.
- Storage: Store the board in a cool, dry environment, away from direct sunlight, extreme temperatures, and high humidity. Use anti-static bags if available.
- Power Supply: Always use a stable 5V power supply within the specified voltage range (4.75-5.25V) to prevent damage to the board.
- Firmware Updates: Regularly check for and apply firmware updates from the manufacturer or community to ensure optimal performance and security.
Troubleshooting
- Board Not Detected by Computer:
- Ensure the USB cable is securely connected to both the board and the computer.
- Verify that the correct USB-to-serial drivers are installed for your operating system.
- Try a different USB port or cable.
- Program Upload Fails:
- Check if the correct board type (ESP32 Dev Module) and COM port are selected in your IDE.
- Ensure no other application is using the serial port.
- Sometimes, pressing the "BOOT" button while connecting or during upload can help.
- Display Not Working:
- Verify that your code correctly initializes and sends data to the display.
- Ensure the board is receiving adequate power.
- WiFi/Bluetooth Connectivity Issues:
- Check your network credentials (SSID, password) in your code.
- Ensure the board is within range of the WiFi access point or Bluetooth device.
- Verify that the antenna is not obstructed.
