## Description

2.8 inch 240x320 color TFT screen with resistive touchscreen, ideal for graphical interfaces on STM32 ALIENTEK projects. ILI9341 controller, SPI communication with only 4 IO pins, offers 65K colors and white LED lighting. Includes microSD slot on the back for files and images, operates at 3.3V or 5V and has a 34-pin connector.
The 2.8 inch color TFT SPI LCD display is a practical solution for embedded projects and control applications based on STM32 and C51 platforms. With a resolution of 240x320 pixels, ILI9341 driver IC, resistive touch, and an integrated SD Card adapter on the back of the PCB, this module provides a clear and easy-to-use graphical interface for menus, data display, control panels, or HMI applications. The screen uses white LED backlighting, displays up to 65K colors, and supports default 16-bit operation with the option to select 8-bit mode as well.
The module is compatible with ALIENTEK STM32 Mini, Elite, WarShip, Explorer, and Apollo development boards, being especially designed for use with STM32 platforms. Besides graphical display, the screen integrates a resistive touch function for direct interaction and an SD Card slot to extend functionality in projects requiring file, image, or data storage. Thanks to its compact construction and efficient interface, the module is suitable for industrial, educational, and advanced development projects.
Attention, the display has 34 pins and is not directly attachable to Arduino boards. For the Mega board, compatible displays use 40 pins.

Usage:
The display is used in development projects based on STM32 or C51 platforms where graphical interfaces, menus, system parameters, or real-time data display are needed. The module connects to the control board via dedicated pins for LCD command, data bus, and touch interface, and correct operation requires following the recommended pin configuration and supply voltages. The resistive touch allows direct interaction with the application, useful for control panels, test equipment, industrial projects, or embedded systems with visual interfaces.
The integrated SD Card slot on the back can be used for storing or reading files required by the application, and the included pen helps with precise operation of the touch screen. This display is not intended for direct mounting on Arduino boards, as it uses a 34-pin connector. For proper integration, it is recommended to verify electrical and mechanical compatibility with the development board used.
