XC4430
Most of the Duinotech models use two chipsets, one for the main controller, one for USB communication. The Duinotech Leonardo combines both these functions into a single IC, which opens to door for more advanced USB functions. The development board also boasts more analogue inputs (12), and an extra PWM channel.
