2.8″ TFT LCD Display Module SPI 240×320 Pixels with ILI9341 Driver & SD Card Slot

Quick Introduction Upgrade your interface from simple text to full-colour graphics with the 2.8″ TFT LCD Module. Powered by the robust ILI9341 driver, this display delivers a crisp 240×320 resolution with 65K colours. Unlike older parallel displays that hog 10+ pins, this module uses a streamlined 4-Wire SPI interface, leaving plenty of I/O available for your sensors and actuators. It also includes an onboard full-size SD card slot, making it easy to load bitmaps and logs directly from the screen.

Detailed Specifications

• Driver IC:
• Resolution: 240 x 320 Pixels (RGB).
• Interface: 4-Wire SPI (Serial Peripheral Interface).
• Display Size:8-inch Diagonal.
• Color Depth: 18-bit (262K) / 16-bit (65K) Colors.
• Operating Voltage (VCC):3V – 5.0V (Onboard 3.3V Regulator).
• Logic Voltage: 3V ONLY (Not 5V Tolerant).
• Backlight: LED (PWM controllable or 3.3V fixed).
• Storage: Onboard SD Card Slot (SPI).

Quality Advantage & Differentiation: Why choose this SPI TFT?

1. Pin Efficiency: By using SPI, you only need 4-5 control pins (SCK, MOSI, CS, DC, RST) compared to the 8-16 pins required by parallel displays.
2. Broad Library Support: The ILI9341 is one of the most supported drivers in the maker ecosystem. It works flawlessly with Adafruit_ILI9341, TFT_eSPI (for ESP32), and Ucglib.
3. Versatile Power: The onboard voltage regulator allows you to power it from 5V (Arduino) or 3.3V (ESP32/STM32) seamlessly, though logic levels must be handled carefully.

Key Applications & Usage

• IoT Dashboards: Display MQTT data, graphs, and connection status on ESP32 devices.
• Game Consoles: Build retro handheld games using the fast SPI refresh rates (especially with DMA on ESP32).
• Medical Devices: Create clean, readable interfaces for heart rate monitors or digital thermometers.
• Photo Frames: Cycle through bitmaps loaded from the onboard SD card.

What’s Included & Required

• Included: 1x 2.8″ TFT LCD Display Module (SPI).
• Required: Microcontroller (Arduino/ESP32), Jumper Wires, Logic Level Shifter (if using 5V Arduino).

The “Virtual Technician” Support Panel

• ⚠️ CRITICAL SAFETY WARNING:
  • 3V Logic Only: The VCC pin can take 5V, but the Data Pins (SCK, MOSI, CS, DC, RST) are 3.3V Logic. Connecting these directly to a 5V Arduino Uno will eventually damage the screen or cause “White Screen” artefacts.
  • Solution: Use a Logic Level Converter module or 1.2kΩ/2.2kΩ voltage divider resistors on the data lines.
  • Touch Function: This specific SKU is the Non-Touch While the PCB may have pins labelled “T_CLK” or “T_CS”, the touch digitiser glass and XPT2046 controller are likely not installed/active on this economy model.
• Pinout Reference:
  • VCC:3V – 5V Power Input.
  • GND:
  • CS: Chip Select (Low Enable).
  • RESET: Reset (Low Active).
  • DC/RS: Data/Command Selection.
  • SDI (MOSI): SPI Data Input.
  • SCK: SPI Clock.
  • LED: Backlight (3.3V for ON).
  • SDO (MISO): SPI Data Output (Rarely used for display, used for SD card).
