3.2 Inch TFT LCD Touch Screen Module 240×320 ILI9341 SPI Arduino UNO Mega

🔧 3.2 Inch TFT LCD Touch Screen Module | AuscomTech

This is a 3.2-inch colour TFT LCD display module with resistive touch input, SPI communication, and an onboard SD card socket.

It uses the ILI9341 driver IC and provides 240 × 320 pixel resolution with RGB 65K colour support for graphics, menus, data readouts, and embedded control interfaces.

Typical use includes Arduino UNO, Mega2560, ESP32, STM32, Raspberry Pi, and other microcontroller projects requiring a compact colour display with touch control.

⭐ Key Features

• Colour TFT Display – 240 × 320 resolution with RGB 65K colour output for clear graphics and text.
• Touch Control – Resistive touch input allows interactive menus, buttons, and control panels.
• ILI9341 Driver – Widely supported by common Arduino and embedded graphics libraries.
• SPI Interface – 4-wire serial connection uses fewer IO pins than parallel LCD modules.
• SD Card Socket – Onboard storage slot for images, fonts, configuration files, or data display projects.
• Backlight Pin – LED control pin allows software backlight control or fixed always-on operation.
• 14-Pin Header – Provides display, touch, and SPI signal access for flexible wiring.
