2.8″ TFT Touch Shield for Arduino w/Capacitive Touch (ID: 1947) Adafruit

DESCRIPTION

Add some sizzle to your Arduino project 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 backlights) and colourful (18-bit 262,000 different shades)! 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 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 other resistive touchscreens available. 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. 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 the uSD card if you want to read images off of it.

FEATURES

• 2.8″ diagonal colour touchscreen TFT
• 240×320 resolution, 18-bit (262,000) colour – the library uses 16 bit colour mode
• ILI9341 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 analogue 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 backlights. On by default but you can connect the transistor to a digital pin for backlight control
• Single-touch capacitive touch bonded on top
