3.5″ Touch LCD Shield for Arduino
Add a crisp 3.5″ touchscreen TFT LCD display to your Arduino project with this 480×320 display shield from Waveshare!
This display comes pre-assembled and is designed to be used with the Arduino Uno or a pin-compatible board. The display slots into your Arduino’s female headers and is powered by the Arduino board as well.
The display includes resistive touch which is useful for interfacing with your project’s menus and options, with PWM backlight control for adjusting brightness to a comfortable level. The onboard microSD slot can be used for storing images for your display project. The display is controlled by SPI, keeping more of your IO pins free.
