2.4 Inch TFT Touchscreen LCD Display for Arduino Uno - Compoden
2.4 Inch TFT Touchscreen LCD Display for Arduino Uno
This 2.4-inch TFT LCD module adds a full-colour graphical interface and resistive touch input to your Arduino Uno. With a 240×320 pixel resolution, it’s suitable for handheld instruments, sensor dashboards, and simple control panels. The display uses the proven ILI9341 driver, so it works with a wide range of Arduino libraries right out of the box.

What You Can Build With This
- A portable weather station showing temperature, humidity, and forecasts on a colour screen
- A touch-controlled menu interface for an IoT home automation controller
- A simple graphics demo or mini arcade game using Adafruit GFX library
- A sensor data logger with real-time scrolling graphs
Compatibility
The display is designed for 3.3 V logic but the signal pins tolerate 5 V, so it works directly with Arduino Uno, Mega, and Nano. It pairs easily with the Adafruit_ILI9341 and MCUFRIEND_kbv libraries. The touch controller shares the SPI bus, requiring two extra analog pins for X and Y coordinate readout.
Wiring Notes
Connect VCC to 3.3 V on the Uno, GND to GND. Link SCK to pin 13, MOSI to pin 11, CS to pin 10, DC to pin 9, and RESET to pin 8. Touch pins T_CLK, T_CS, T_DIN, T_DO, T_IRQ can go to analog pins A0–A4. Keep wiring short and avoid placing the module near high-current circuits to prevent touch glitches.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi?
Yes, with a level shifter for the 5 V pins. You can drive it via SPI using the same ILI9341 driver and the fbtft kernel module. Touch control works over the analog interface with an external ADC.
Which library should I use for Arduino Uno?
Use the MCUFRIEND_kbv library for quick setup. Include the Adafruit_GFX library for drawing shapes and text. For touch, a lightweight routine reading the analog pins works without additional libraries.
Does the touchscreen need calibration?
Resistive touch panels can drift slightly. A simple calibration sketch mapping raw X-Y values to screen coordinates is recommended. Once calibrated, touch accuracy is within a few pixels.
