Duinotech Leonardo r3 Development Board for Arduino

Arduino Compatible

Most of the Duinotech models use two chipsets, one for the main controller, one for USB communication. 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.
