DIYables 3.2 Inch TFT LCD Display Screen 320x240 SPI Non-Touch for Arduino ESP32
Click to zoom
Quick Overview
This DIYables 3.2 inch TFT LCD display module uses the ILI9341 driver chip with a 320x240 pixel resolution and 65K color depth, delivering clear, colorful graphics over a simple 4-wire SPI interface. As a non-touch, display-only module, it's built for applications that need visual output without a touch panel.
The module communicates over SPI (VCC, GND, CS, RESET, DC, SDI/MOSI, SCK, LED, SDO/MISO), keeping wiring simple and freeing up GPIO pins compared to parallel-interface displays. It's compatible with Arduino, ESP32, ESP8266, and Raspberry Pi boards.
An onboard microSD card slot on the back of the PCB shares the same SPI bus as the display, so you can load bitmaps, fonts, icons, and logged data straight from a card without adding a separate SD module or extra wiring.
This display is well suited for instrument panels, sensor data dashboards, IoT status screens, and embedded user interface projects that need a compact, colorful, non-touch graphical display.

※ NOTE THAT:
This is a non-touch module. The PCB carries T_CLK, T_CS, T_DIN, T_DO, and T_IRQ pads because it shares a layout with the touch version of this display, but no touch panel is fitted and those pins are not functional. Use the display pins only: VCC, GND, CS, RESET, DC, SDI (MOSI), SCK, LED, SDO (MISO).
The bundled tutorials and library are shared with the touch models in this family, so some are titled "TFT LCD Touch Display". The display code applies to this module; ignore the touch sections.
This display's logic voltage has not been confirmed for this listing. Verify the module's operating voltage (3.3V or 5V-tolerant) before wiring to a 5V board, and add a level converter on the MCU-driven signal lines if needed.
