FAQ
Q: How do I control the 4.3 inch UART display?
A: Super simple – connect via UART (TX/RX/GND), send commands like text strings or hex instructions. We provide full protocol docs and examples.
Q: Can I add touch functionality?
A: Yes! We support resistive or capacitive touch, fully integrated.
Q: Is customization possible?
A: Absolutely – resolution, brightness, interface, even add features like buzzer or SD card slot.
Q: What's the power requirement?
A: Typically 5V or 12V, low consumption for embedded use.
Q: Do you support RS485 for longer distances?
A: Yes, we can configure for RS232/485/TTL.
Q: Can I use this 4.3 inch UART TFT display outdoors or in bright light?
A: With 250 cd/m² brightness, it's fine for indoor/industrial use. For outdoor applications, we can customize higher brightness (up to 1000+ cd/m²) or add anti-glare options – just let our engineers know your environment.
Q: The screen shows garbled text or nothing at all – what's wrong?
A: This is usually a baud rate mismatch or wiring issue. Double-check your TX/RX connections (don't cross them incorrectly), ensure shared ground, and confirm the same baud rate/parity settings on both sides. A quick reset often fixes it too.
