Introduction

This is a multifunctional Arduino/Arduino Mega compatible resistive touch screen. It can be used as display device or sketch pad. With a SD card module integrated also on this shield, this shield reserves great room for other expansions to your project.

Features

  • Big screen for easy and comfortable experience
  • Backlight controllable via programming
  • 65535 rich colors display
  • SPI pin-saving communication method
  • Full screen touch active range
