The Duinotech Lite combines both these functions into a single IC, which opens to door for more advanced USB functions. Now you can have your DuinoTECH Lite emulate a computer keyboard, mouse, joystick and many other types of input device. The DuinoTECH Lite also boasts more analogue inputs (12), and an extra PWM channel.
