Product Description:
The 2.4 Inch TFT LCD Touch Display Module (MAR2406) is a full-color, high-resolution display module designed for Arduino UNO and Mega2560 boards. Featuring the ILI9341 driver, it offers a 320x240 pixel resolution, 65K RGB color depth, and a resistive touch panel, making it perfect for creating graphical user interfaces and interactive embedded projects.
With its 8-bit parallel interface, this module delivers faster refresh rates than SPI alternatives, while the onboard level-shifting IC ensures compatibility with both 5V and 3.3V systems. It also includes an SD card slot for media expansion and comes with a complete Arduino library and example programs for rapid development.
Key Features:
Full-Color Display: 2.4-inch TFT LCD with RGB 65K colors for vibrant visual output.
High Resolution: 320x240 pixels with a clear and crisp interface.
Touch Functionality: Integrated resistive touch panel for user interaction.
Fast 8-Bit Parallel Interface: Delivers quicker screen updates compared to SPI modules.
Multi-Platform Support: Compatible with Arduino UNO, Mega2560, and other 3.3V/5V logic level boards.
Built-in SD Card Slot: For loading external resources such as images or fonts.
Level-Shifting IC: Ensures safe operation with both 3.3V and 5V MCUs.
Military-Grade PCB Standards: Built for durable, long-term stable performance.
Extensive Documentation & Driver Support: Includes Arduino libraries, sample codes, schematics, and datasheets.

How to use on Arduino
- Step 1: Download the test program
- Download the Arduino test program from the Program Download column
- For a description of the relevant test procedures, please refer to the test program documentation in the package
- Step 2: Connect the Arduino development board
- Plug the module directly into the Arduino development board ( Do not plug in?)
- After the module is plugged in, power on the Arduino board
- Step 3: Copy the dependent library
- Make sure the Arduino IDE is installed on your computer (if it is not installed: Arduino IDE download URL)
- After installing the Arduino IDE, you need to copy the dependent library to the Arduino project directory as follows:
- (1) Decompress the downloaded test package
- (2) Copy the dependent libraries in the Install libraries directory in the package (shown below) to the libraries folder
- of the Arduino project directory （ Don't know the Arduino project directory?）
- Step 4: Compile and download the program to the development board
- Open the sample in the Example directory of the package to test, compile and download（ Don't know how to compile and download?）
- Step 5: Observe the running of the program
- After the program is downloaded, run it directly and observe the running status. If it can be displayed normally, the program runs
- successfully, as shown in the following figure (take the colligate_test test program as an example):
