Why Choose This Display

This 3.5 inch SPI TFT touch display is ideal when you need a balance of size, color quality, and low pin count. The SPI interface keeps wiring simple and saves MCU pins, while the resistive touch panel offers reliable input for industrial, DIY, or educational applications. It is well suited for GUIs, control panels, IoT dashboards, and robot interfaces.

Applications

• Touchscreen interfaces for Arduino, ESP32, and Raspberry Pi projects
• Embedded graphical user interfaces (GUIs) and control panels
• Data monitoring, industrial control, and IoT dashboards
• Robotics, automation displays, and smart home panels
• Educational kits and DIY electronics projects

Pinout and Typical Wiring (SPI Mode)

Exact pin labeling may vary by module. Typical connections:

• VCC: 3.3V to 5V power
• GND: Ground
• SCK / SCL: SPI clock
• MOSI / SDA: SPI data (MCU to display)
• MISO: SPI data (display/touch to MCU) if required
• CS / CS_LCD: Chip select for display
• DC / RS: Data/Command selection
• RST: Reset
• T_CS: Touch controller chip select (XPT2046)
• T_IRQ: Touch interrupt (optional, for touch-ready interrupts)

Library Support and Software

• Works with popular display libraries such as TFT_eSPI and MCUFRIEND_kbv.
• Compatible with ILI9488 drivers; some projects may also use Adafruit or community ILI9486 drivers with configuration.
• Touch is supported by XPT2046 drivers and libraries for Arduino and ESP32. Calibration routines are recommended for best accuracy.
• Example resources: TFT_eSPI setup files, XPT2046_Touchscreen libraries, and community wiring guides.

Mechanical and Mounting Notes

• Compact design fits handheld enclosures and small instrument panels.
• Mounting holes and bezel dimensions vary by supplier; confirm mechanical drawings before final enclosure design.

Integration Tips

• Use level shifting or a 3.3V MCU to ensure reliable logic levels when running at 3.3V.
• Enable double buffering in supported libraries for smoother animation and full-screen updates.
• Run touch calibration on first boot and store calibration values in nonvolatile memory.
