Add a 2.8" touch screen display to your Arduino project for a compact programmable interface!
This TFT display from Waveshare has a 320x240 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, 320x240 resolution
- Standard Arduino interface, compatible with development boards like : Arduino UNO, Leonardo, UNO PLUS, NUCLEO, XNUCLEO
- Onboard stand-alone touch controller, better touching than solutions that use AD pins directly for touch control
- Micro SD slot, provides an easy way to store photos for displaying
- Controlled via SPI, only a few Arduino pins are used
- Backlight adjustable by program, lower power consumption
