Overview

About 2.4 inch TFT LCD Touch Display Module 240x320 ILI9341 (SPI).

The 2.4 inch TFT LCD Touch Display Module packs a 240x320 pixel color panel driven by the ILI9341 controller, adds a resistive touch layer and an onboard microSD card slot, all communicating over SPI. It is the go-to color touchscreen for makers who have outgrown a small 1.8 inch screen and want real GUI capability from an Arduino UNO, MEGA or ESP32.

With 240x320 resolution and 65K colors, it comfortably renders menus, buttons, graphs and images. The resistive touch panel (typically read by an XPT2046/TSC2046 controller) lets you build touch-driven interfaces, while the microSD slot lets you load bitmap images and log data. Both share the same SPI bus, keeping wiring simple.

Its popularity in India comes from strong library support (TFT_eSPI, Adafruit ILI9341, plus XPT2046 touch libraries) and its versatility across UNO, MEGA and the very common ESP32. At around Rs 550 it hits a sweet spot of size, resolution and touch for hobby HMIs and college projects.

Buying guide

How to choose.

Choose this 2.4 inch ILI9341 touch module when you need a color screen plus touch input and storage in one board. It is a big step up from the 1.8 inch ST7735 (BOTBIT-DSP-08) but still budget-friendly. If you want an all-in-one board with the microcontroller already integrated, consider the CYD ESP32 board (BOTBIT-DSP-12) instead.

Pair it with an ESP32 for the smoothest performance and WiFi connectivity, or an Arduino MEGA if you prefer 5V AVR. The touch panel needs its own library (XPT2046_Touchscreen or the touch functions in TFT_eSPI) and a calibration step for accurate taps.

Because display, touch and SD all use SPI, plan your CS pins carefully. On ESP32, TFT_eSPI's User_Setup lets you assign each chip-select cleanly. Keep in mind resistive touch needs firm single-point presses and works well with the included stylus-style pointer or a fingernail.

FAQ

Common questions.

Will this SPI module work on an Arduino UNO?

Yes, the SPI version works on UNO, but the UNO's limited RAM and 5V logic mean slower refresh and the need for care with 3.3V signals. For fast, smooth graphics and touch, an ESP32 or MEGA is a better match.

Do the display and touch use the same library?

The display uses TFT_eSPI or Adafruit ILI9341, while the resistive touch uses a separate driver such as XPT2046_Touchscreen. TFT_eSPI can also handle the XPT2046 touch, letting you manage both from one library on ESP boards.

Is the touch capacitive or resistive?

It is a resistive touch panel. It responds to pressure from a fingertip, fingernail or stylus and needs a one-time calibration in software for accurate coordinates. Resistive touch registers a single point at a time.

Can I read images and log data to the microSD slot?

Yes. The onboard microSD (TF) slot shares the SPI bus with the display. You can load BMP images to show on screen and write CSV or text logs using the standard SD library, assigning the SD its own chip-select pin.

Does it need 3.3V or 5V power?

The logic is 3.3V. Many modules include an onboard regulator so VCC can accept 3.3V-5V, but the data lines should be 3.3V. Use level shifting or a 3.3V board like ESP32 to be safe; check your specific variant's markings.

What comes in the box?

You get the 2.4 inch ILI9341 touch display module with the microSD slot and touch panel. A touch stylus and jumper wires are usually not included, so add them to your order if needed.
