This is a design based on the Ruiz's brothers Emoji Keyboard project adapted to create a case for a switch interface to house mono jack ports, on/ off power, battery pack, and Adafruit's Bluefruit express board. The switch interface is used by persons with motor difficulties to access custom switches in order to interact with a computer or mobile device.
