2.8" TFT Touch Shield for Arduino with Capacitive Touch
Description
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 Arduino UNO. The capacitive touchscreen controller uses I2C but you can share the I2C bus with other I2C devices.
The shield is fully assembled and tested by Adafruit. Simply plug it in and load up Adafruits library. Works best with any classic Arduino UNO.
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, 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.
Specifications
240x320 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.
Works with any classic Arduino.
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
Board has the I2C pullups connected to IOREF rather than 5V so it's more compatible with 3.3V boards.
