MotoDriver 3

With the MotoDriver3 you have the possibility to control and power up to four DC motors or two stepper motors. The connected motors are controlled via the PCA9634 chip, which provides an I2C interface.

The MotoDriver3 offers an integrated voltage conversion, which allows to provide an adjustable voltage of 3.3V or 5V for microcontrollers and selected single board computers. All that is required is to connect a voltage source to the "DC in" input.

Thanks to the MotoDriver3, there is no need for additional power supplies for the motors or the use of large amounts of cables. The expansion board allows precise control of the motors with a constant voltage in the range of 4V to 10V.
