3. Setup
3.1. Powering the Display
The NEXTION display can be powered via a Micro USB 5V connection. Ensure you use a stable 5V power supply.
Video 1: Instructions on how to power the Nextion Display via Micro USB 5V.
3.2. Programming the Display via SD Card
To upload your HMI project to the display, you can use an SD card. Ensure the SD card is less than 32GB and formatted as FAT32. Copy the generated .TFT file to the SD card (ensure it's the only file on the card), insert it into the display's SD card slot, and then power on the display. The display will automatically update.

5. Maintenance
To ensure the longevity and optimal performance of your NEXTION HMI Display, follow these maintenance guidelines:
- Cleaning: Use a soft, dry, lint-free cloth to clean the screen. Avoid abrasive cleaners, solvents, or aerosol sprays that can damage the display surface.
- Handling: Handle the display by its edges. Avoid applying excessive pressure to the screen, especially the capacitive touch surface.
- Environment: Operate the display within its specified temperature and humidity ranges. Avoid exposure to direct sunlight, extreme temperatures, or high moisture.
- Power: Always use a stable 5V power supply. Incorrect voltage can damage the device.
6. Troubleshooting
If you encounter issues with your NEXTION HMI Display, refer to the following common problems and solutions:
- Display Not Powering On:
- Ensure the 5V power supply is correctly connected and providing sufficient current.
- Check the power cable for any damage.
- Screen Remains Blank After Programming:
- Verify that the .TFT file was correctly copied to the SD card and that the card is properly inserted.
- Ensure the SD card is formatted as FAT32 and is less than 32GB.
- Confirm that the display model in your Nextion Editor project matches your physical display.
- Touch Screen Unresponsive:
- Check for any physical obstructions or debris on the screen surface.
- Ensure the display is receiving adequate power.
- Recalibrate the touch screen if the option is available in your project.
- Communication Issues with Microcontroller:
- Verify the TX/RX and GND connections between the display and the microcontroller.
- Ensure the baud rate set in your microcontroller code matches the baud rate configured in your Nextion project.
- Check that the correct serial port is selected in your development environment.
