Adafruit 2.8″ TFT Touch Shield
Spice up your Arduino project with a touchscreen display shield with built in microSD card connection. This TFT display 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. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
This is the newest version from Adafruit – it has been updated from their original v1 shield to an SPI display – its a tiny bit slower but uses a lot less pins and is now much easier to use with Mega & Leonardo. Adafruit also includes an SPI touchscreen controller so you only need one additional pin to add a high quality touchscreen controller. This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller.
The shield ships fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up the Arduino Library Adafruit provides (see links below). It will be up and running in under 10 minutes! The shield 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.
- 240×320 resolution, 18-bit (262,000) color
- The display uses digital pins 13-9. Touchscreen controller requires digital pin 8. microSD pin requires digital #4.
- Onboard 3.3V @ 300mA LDO regulator, current draw depends on usage but is about 100mA for the display and touchscreen
- High speed SPI display with digital SPI touchscreen driver
- Works with any classic Arduino ‘328. Solder closed three jumpers to use the ICSP header for use with Leonardo or Mega
- 4 white LED backlight. On by default but you can connect the transistor to a digital pin for backlight control
