Seeed Studio BeagleBone® Green LCD Cape with Resistive Touch

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.
