Common Problem
How do I program the UI on this 2.4 inch UART display?
Use our free GUI design software – drag-and-drop elements, then download via SD card or UART. No advanced coding required.
Can I customize the resolution or add features?
Yes! Everything from backlight brightness to interface type is customizable.
Why is my 2.4 inch UART display showing nothing or just a white/black screen?
This is a super common issue! First, double-check your power supply-make sure it's stable 3.3V or 5V (depending on your module variant) and providing enough current (around 200-300mA with backlight on).
The capacitive touch on my 2.4 inch UART display isn't responding-what's wrong?
Touch issues often stem from calibration or interference. Our capacitive panels are pre-calibrated, but in noisy environments (like near motors), add shielding or grounding. Also, ensure you're using the latest firmware-touch events are reported back via UART, so check if your code is reading them correctly.
