6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the display surface. Avoid abrasive cleaners or solvents.
- Handling: Handle the module with care to prevent damage to the screen or electronic components. Avoid applying excessive pressure to the display.
- Storage: Store the module in a dry, dust-free environment away from extreme temperatures and direct sunlight.
7. Troubleshooting
- Issue: Module does not power on or behaves erratically.
- Solution: Ensure you are using a stable 5V/1A power supply. Insufficient power can cause instability. Verify that the USB cable used is a USB-A to Type-C cable, not a Type-C to Type-C cable, as some Type-C to Type-C cables may not provide adequate power or data transfer for this module.
- Issue: Computer does not recognize the module.
- Solution: Install the CH340 driver. This driver is necessary for your computer to communicate with the module's serial interface.
- Issue: Programming or flashing errors.
- Solution: Double-check your wiring connections, especially the JST1.25 4-pin TTL serial interface. Ensure the correct development environment (Arduino IDE, ESP IDE, Micropython, Mixly) is configured and the appropriate libraries are installed. Refer to the official documentation for specific flashing procedures.
- Issue: Cannot find I2C pins.
- Solution: While the module integrates high-speed SDIO, SPI, and UART, specific I2C pins are not explicitly labeled in the provided diagrams. Please consult the detailed pinout documentation or schematics available via the download links for precise I2C pin locations if required for your application.
