2.8″ TFT Touch Shield for Arduino with Capacitive Touch
This 2.8″ TFT Touch Shield for Arduino with Capacitive Touch is big (2.8″ diagonal) bright (4 white-LED backlight) and colorful (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 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.
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.
- 240×320 resolution, 18-bit (262,000) color – our library uses 16 bit color mode
- 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
