## Description

3.2 inch TFT color screen with resistive touch, 240x320 resolution and ILI9341 driver, ideal for graphic interfaces on STM32 and C51 projects. Offers 65K colors display on 8 or 16 bit parallel bus, includes microSD reader on the back for resources and logging, has integrated regulator for 3.3-5V power supply and XPT2046 touch controller for precise interaction.
The 3.5-inch color LCD touch display is a practical solution for embedded projects and development systems based on STM32, providing clear display in 65K colors and support for RGB interface in 8 and 16 bits.
It is compatible with ALIENTEK STM32 Mini, Elite, WarShip, Explorer, and Apollo development boards, being suitable for applications that require graphical interface, touch commands, and real-time data display. The module uses the ILI9341 graphic controller for stable and precise rendering, and the XPT2046 touch controller allows quick and intuitive interaction.
Includes an SD card reader on the back for functionality expansion and comes with a stylus for easier operation. The module has an integrated 3.3V voltage regulator, allowing power supply at both 3.3V and 5V.
Attention, this display has 34 pins and is not directly compatible with standard Arduino boards. For the Arduino Mega board, 40-pin variants are required.

Usage:
The display is recommended for automation projects, graphical interfaces for electronic equipment, control systems, and educational or industrial applications based on STM32 microcontrollers.
It connects to compatible boards via parallel interface, and the touch function allows direct control from the screen. For proper operation, it is important to check the compatibility of the pin count and the board used before assembly. The SD card reader can be used for storing images, files, or other data required by the application.
