2.8″ Touch LCD Shield for Arduino
Add a 2.8″ touch screen display to your Arduino project for a compact programmable interface!
This TFT display from Waveshare has a 320×240 resolution and is controlled by SPI, meaning only a few pins are used.
The display features a touchscreen for interfaces or project control and includes a micro-SD card slot for image storage (micro-SD card not included).
Features
- Resistive touch screen TFT LCD, 2.8inch, 320×240 resolution
