2.8" TFT Touch Shield for Arduino with Capacitive Touch

Add some pizazz to your Arduino project with a beautiful large touchscreen display shield with built in microSD card slot and a capacitive touchscreen. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (262,000 different colors!) 240x320 pixels with individual pixel control. It has a lot more resolution than a black and white 128x64 display. As a bonus, this display has a capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This shield is the capacitive version as opposed to the resistive touchscreen we also sell. This touchscreen doesn't require pressing down on the screen with a stylus, and has a nice glossy glass cover. It is a single-touch display.

This shield uses SPI for the display and SD card and is easier to use with UNO, Mega & Leonardo Arduino's. The capacitive touchscreen controller uses I²C but you can share the I²C bus with other I²C devices.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you'll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Duemilanove/Diecimila). Solder three jumpers and you can use it at full speed on a Leonardo or Mega as well.

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, 2 shared I²C pins for the touchscreen controller and another pin for uSD card if you want to read images off of it.

Of course, we wouldn't just leave you with a datasheet and a "good luck!" - we've written a full open source graphics library that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

Specifications

  • 2.8" diagonal color touchscreen TFT
  • 240x320 resolution, 18-bit GPU, 262,000 color - our library uses 16 bit color mode
  • ILI9341 (datasheet) controller with built in video RAM buffer
  • FT2606 touch screen controller
  • High speed SPI display with digital I2C touchscreen driver
  • The display uses digital pins 13-9. Touchscreen controller requires I2C pins SDA and SCL. microSD pin requires digital #4. That means you can use digital pins 2, 3, 5, 6, 7, 8 and analog 0-5. Pin 4 is available if not using the microSD
  • Works with any classic Arduino '328. Solder closed three jumpers to use the ICSP header for use with Leonardo or Mega
  • Onboard 3.3V @ 300mA LDO regulator, current draw depends on usage but is about 100mA for the display and touchscreen
  • 4 white LED backlight. On by default but you can connect the transistor to a digital pin for backlight control
  • Single-touch capacitive touch bonded on top
