4. Application Guidelines & Critical Notes

Intended Use

• Industrial control panels and human-machine interfaces (HMIs)
• Smart home control systems and IoT display nodes
• Embedded systems requiring serial-controlled display with touch input
• Any application requiring a compact, serial-controlled display with capacitive touch

Critical Design Considerations

1. Serial Interface Selection: This module uses a UART/RS232 serial interface controlled by a T5L ASIC. The host must communicate via serial commands. UART2 and UART4 can be configured as TTL/CMOS (ON) or RS232 (OFF). UART4 requires OS configuration before use.
2. Power Supply: Provide a stable 5V DC power supply with at least 1A current capability. Operating voltage range is 4.5V~5.5V. At maximum backlight brightness, current draw is 240mA.
3. Brightness Control: The module supports 100-level brightness adjustment. Avoid using the 1%~30% range as flickering may occur.
4. Image Sticking Prevention: Use dynamic screen saver wallpapers to prevent afterimages from long-term fixed image display.
5. Mechanical Integration: Module outline: 143.5mm × 80.9mm. Active area: 108.0mm × 64.8mm. View area: 110.6mm × 66.9mm. Use location holes as position reference.
6. Baud Rate Configuration: The module supports baud rates from 3150 to 3225600 bps, with a typical value of 115200 bps.

Handling & Compliance

• The module is RoHS compliant.
• Observe standard ESD precautions during handling and assembly.
• The module contains fragile glass and sensitive electronics – handle with care.
• Avoid applying excessive force to the display surface or touch panel.
• Ensure proper grounding during operation and handling.
