2.8" TFT Touch Shield for Arduino w/Capacitive Touch
Your Arduino project will no long be the same boring prototype after being equipped with a beautiful large touchscreen display shield with built in microSD card connection and a capacitive touchscreen. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As an addition, it has a built in capacitive touch screen very similar to the one you have on your smartphone/tablet device.
The single-touch display capacitive version does not require a stylus and has a nice glossy glass cover.
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! Recently, this model has provided great reviews from GCC users in Dubai, UAE, Oman, Qatar, and other developed and developing neighboring countries. 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!
- 2.8" diagonal color touchscreen TFT
- 240x320 resolution, 18-bit (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
