Overview
3.2 Inch TFT SPI LCD Display with Touch Panel 240×320 ILI9341
Create interactive graphical interfaces for your electronics projects with the 3.2 Inch TFT SPI LCD Display with Touch Panel. Featuring a 240×320 pixel color display and the widely supported ILI9341 driver, this module provides a practical combination of visual output and touch-based interaction.
The display communicates through an SPI interface, making it suitable for many popular microcontroller development platforms. The integrated touch panel allows users to interact directly with menus, buttons, controls, and graphical interfaces without requiring additional physical input devices.
Its larger 3.2-inch screen provides more usable display area than many small TFT modules, making it suitable for dashboards, monitoring systems, portable instruments, control panels, and interactive DIY projects.
The module is ideal for Arduino, ESP32, STM32, Raspberry Pi-compatible projects, IoT devices, robotics, automation systems, educational electronics, and custom touchscreen interfaces.

Product Technical Information
Technical Details
3.2 Inch 240×320 ILI9341 TFT Touch Display
The 3.2 Inch TFT SPI LCD Display with Touch Panel is a color graphical display module designed for embedded electronics and interactive projects. It combines a 240×320 pixel TFT LCD with an integrated touch panel, providing both visual output and touch-based input.
240×320 Color Display
The 240×320 pixel resolution provides sufficient detail for displaying:
- Text
- Icons
- Menus
- Buttons
- Graphs
- Sensor readings
- Images
- Status information
- Graphical dashboards
The display orientation can generally be configured in software, allowing the screen to be used in either portrait or landscape layouts depending on the application.
ILI9341 Display Controller
The module uses the popular ILI9341 TFT display controller, which is supported by a variety of libraries and development platforms.
This makes it convenient for developers and makers building graphical interfaces with microcontrollers such as Arduino and ESP32.
SPI Interface
The display uses an SPI communication interface, providing a practical connection method for microcontroller-based projects.
SPI allows the display to communicate with the controller using a relatively small number of signal lines, although exact pin requirements can vary depending on the module design and touch controller.
Integrated Touch Panel
The built-in touch panel allows the display to function as an interactive input device. Instead of relying solely on buttons or switches, users can interact directly with on-screen controls.
This is useful for:
- Touch menus
- On-screen buttons
- Configuration panels
- Control interfaces
- Monitoring dashboards
- Interactive projects
The exact touch technology and controller can vary between module versions, so the touch-controller specifications should be checked for the specific board.
Applications
The display is suitable for:
- Arduino projects
- ESP32 projects
- STM32 projects
- IoT dashboards
- Robotics
- Home automation
- Industrial prototypes
- Portable instruments
- Sensor monitoring
- Touch control panels
- DIY gaming projects
- Educational electronics
- Embedded graphical interfaces
Larger Interactive Display
The 3.2-inch screen provides a larger interface compared with compact 1.3-inch or 1.8-inch displays, making it easier to create more detailed graphical interfaces and touch controls.
Note: Different 3.2-inch ILI9341 modules may have different pinouts, touch controllers, operating-voltage requirements, and library compatibility. Verify the module's specific specifications before connecting it to a development board. Do not assume that every pin is 5V tolerant.
