Seeed Studio BeagleBone® Green LCD Cape with Resistive Touch

Green LCD Cape with Resistive Touch is designed for SeeedStudio Beagle bone® Green or Beagle bone Black with a compact 5-inch LCD which is smaller than a 7-inch one but provides a resolution of 800x480 using a layer of 4-wired resistive touchscreen for user interactions. It's easy to setup by just connecting 2x46 pin headers to SeeedStudioBeaglebone®Green/Beaglebone®Black, which provides everything the cape requires such power supply and display signals. In addition, the cape can be powered by the built-in micro USB on the back. Buttons below the screen, LEFT, RIGHT, UP, DOWN and ENTER, provide an alternative way to interact with your screen. Two LEDs are used for power and user status indication.
