Frequently Asked Questions
Q: Is this TFT LCD display module compatible with Arduino UNO as well as Mega2560?
A: This 3.95" TFT LCD display module is primarily designed for direct plug-in use with the Arduino Mega2560. While it can be interfaced with an Arduino UNO, the UNO has fewer I/O pins, so some creative wiring may be required. The included Arduino library and sample programs are optimized for the Mega2560 platform.
Q: What driver IC does this TFT LCD display module use?
A: This module supports both the ILI9488 and ST7796S driver ICs. The default driver IC shipped is the ST7796S, which provides reliable 480×320 pixel TFT color display output via an 8-bit parallel interface.
Q: Does this display support both 5V and 3.3V microcontrollers?
A: Yes! The module features an on-board 5V/3.3V level-shifting IC, making it fully compatible with both 5V microcontrollers (like Arduino Mega2560/UNO) and 3.3V platforms (like STM32). No additional logic level converter is needed.
Q: Can I use the SD card slot on this display module with Arduino?
A: Absolutely. The built-in SD card slot communicates via the SPI bus (MISO, MOSI, EX_CLK, SD_CS pins) and is easily accessible from Arduino. It's great for storing images, logs, or configuration data in your projects.
