Arduino Shield Compatibility
The module is designed to connect directly to compatible Arduino UNO R3 and Mega2560 boards. The LCD and touchscreen use the board’s available analog and digital pins, while additional pins can remain available depending on how the display and microSD reader are configured.
The shield can also be used with Arduino DUE and other compatible development platforms with the appropriate software and pin configuration.
Touchscreen Interface
The built-in 4-wire resistive touchscreen provides an easy way to interact with your Arduino project. It can be used to create buttons, menus, control panels, numeric inputs, and other touch-based interfaces.
For reliable operation, make sure the required pins are returned to their correct state after touchscreen operations so the LCD can continue communicating properly.
MicroSD Card Reader
A microSD card slot is integrated into the shield, providing convenient storage access for compatible projects. It can be used for reading images, graphics, configuration data, and other files through a suitable software SPI library.
