The PWM30A-Hat is an add on for the Raspberry Pi to be used in robotics or generally for controlling servos and motors in modelmaking. The aim here is to provide an easily programmable interface for the Raspberry Pi. The PWM30A-HAT is particular suitable for Crawler, 4 Wheel and 6 Wheel models. The necessary programming efforts for controlling the motor are minimized to only the I2C interface which means an easy-to-use library. The PWM30A-Hat may also be used to develop own programs via the Raspberry Pi.

Due to its powerful ATxmega128A1U the PWM30A-Hat may be alternatively used standalone. In this case the programming has to be done via the JTAG interface.
