Capacitive touch screen TFT 2,8" 240x320px with microSD reader - Shield for Arduino - Adafruit 1947

Overlay for Arduino with capacitive TFT touch screen. Its diagonal is 2.8", resolution is 240 x 320 px. The display has LED backlighting and individual pixel control, soldered-in connectors, QT port and microSD card reader. Communication is carried out via I2C and SPI interface.

The system is compatible with anyclassic Arduino '328.Theofferedproduct is fully assembled - it has connectors that allow direct connection to Arduino without the need for additional soldering. The use of capacitive screen allows to detect fingerprints anywhere on the screen.

Product compatible with Arduino

The manufacturer provides auser guide with libraries and a sample program tooperate the display.

The displayhas a built-in controller withRAMcaching.Thanks to this, the microcontroller is relieved and does not perform data display operations. The device uses a relatively small number of pins, so it is possible to connect more peripheral devices, LEDs, buttons or sensors to it.

TFT 2.8" 240 x 320 px capacitive touch screen display with microSD reader - Shield for Arduino - Adafruit 1947.

The outputs used by the module:

• Display: 5 SPI digital pins (13 - 9)
• Touch screen controller: 2 common I2C pins (I2C, SDA and SCL)
• MicroSD card: 1 digital pin (4)
• QT port

It remains at your disposal:

• 6 digital pins: 2 - 3, 5 - 8
• 6 analog pins: 0 - 5
• Pin 4 is available if the microSD card is not used

Adafruit provides freegraphic librariesthat make creating shapes and displaying text very easy. A library is available to read where you touch the screen, data is transmitted as X, Y axis values.

To run the touch screen display you need to install additional libraries:

• ILI9341 controller library
• Adafruit GFX graphic library
• Library for the touch function STMPE610

• Resolution: 240 x 320 px, 18-bit colour mode
• Diagonal of the screen: 2,8"
• 4 LED backlit display with adjustable brightness
• Built-in LDO regulator
• MicroSD card reader
• Capacitive screen
• Interface: SPI, I2C
