DFRobot DFR0669 3.5" 480x320 Capacitive TFT LCD Display SPI with MicroSD

The DFRobot DFR0669 is a 3.5-inch IPS TFT LCD display module with a capacitive touch panel, designed for electronic projects requiring a compact and functional full-colour graphical interface.

With 480x320 pixel resolution, 16-bit RGB565 colour depth and ILI9488 graphic driver, this module can display menus, graphics, buttons, images and visual information in microcontroller-based projects.

The touch panel uses the GT911 chip and supports up to 5 capacitive touch points, allowing more intuitive and interactive user interfaces. The main display communication is handled through SPI, making connection to compatible controllers easier.

The module can be powered from 3.3V to 5.5V and is suitable for platforms such as Arduino, ESP32, ESP8266, FireBeetle, boards with compatible GDI interface and other development systems, provided the pinout and communication logic are respected.

In addition to the display and capacitive touch panel, the module includes a MicroSD slot, allowing images or graphic resources to be used from a memory card, depending on the software and library used.

It is a practical solution for IoT projects, human-machine interfaces, control panels, DIY consoles, monitoring systems, automation, prototypes and applications requiring a colour touchscreen display.

Important note

Before use, always confirm the supply voltage, pinout, logic levels, software library, microcontroller compatibility, SPI interface, capacitive touch wiring and total system current consumption.

The DFRobot DFR0669 is a development and integration module, not a standalone finished device. Correct operation requires connection to a compatible controller and suitable programming.

Use of the MicroSD slot depends on correct software, library and wiring. The MicroSD card is not included unless expressly stated otherwise.

Before final installation, it is recommended to bench-test the module, check cable orientation, confirm the pinout and avoid incorrect wiring, as this may damage the display, touch panel or controller being used.
