TFT 2.4 Inch Touch Display Module for Arduino 5V

TFT 2.4 Inch Touch Display Module – Colour LCD Screen for Arduino (5V)

The 2.4 Inch TFT Touch Display Module is a full-colour resistive touchscreen LCD that plugs directly onto an Arduino UNO or Mega shield footprint. With a resolution of 240x320 pixels and an SPI interface, it brings vibrant colour graphics and touch input to your microcontroller projects without complex wiring.

Key Specifications

• Screen Size: 2.4 inches (diagonal)
• Resolution: 240 x 320 pixels (QVGA)
• Display Type: TFT LCD, 65K colours
• Touch: Resistive touchscreen (XPT2046 controller)
• Interface: SPI / 8-bit parallel (driver: ILI9341)
• Operating Voltage: 5V DC
• SD Card Slot: Onboard microSD slot for image storage
• Shield Compatible: Arduino UNO / Mega shield footprint

Compatibility & Use Cases

Directly compatible with Arduino UNO, Arduino Mega, and ESP32 via SPI. Use the Adafruit GFX + ILI9341 library for Arduino, or the TFT_eSPI library for ESP32. Common applications include:

• Graphical user interface (GUI) for IoT control panels
• Real-time sensor data display (temperature, pressure, GPS)
• Touch-controlled menu systems for embedded devices
• Image and bitmap display from SD card
• STEM and engineering project HMI demonstrations

The onboard SD card slot allows storing and displaying BMP images directly from a microSD card for rich graphical interfaces.

Frequently Asked Questions

Does this display plug directly into an Arduino UNO?
Yes. The module follows the Arduino UNO/Mega shield footprint, so it stacks straight onto the board with no jumper wires. For ESP32, connect it over SPI using the TFT_eSPI library.

Which libraries do I need for the display and touch?
Use Adafruit ILI9341 together with Adafruit GFX on Arduino, or TFT_eSPI on ESP32. For touch input, add an XPT2046 touch library and run the one-time calibration sketch.

Is the touchscreen capacitive like a phone?
No, it is a resistive touchscreen. It responds to a finger, stylus or even gloved hands, which makes it reliable for workshop and industrial-style control panels.

Can I show photos or custom graphics on it?
Yes. Save BMP images on a microSD card, insert it into the onboard slot, and render full-colour images and icons directly from the card in your sketch.
