Brushed DC motor drivers are the simplest modules in the sense that all they do is provide power amplification for low-level control signals (e.g. PWM and direction) supplied by the user; on the other hand, that means that the master device to which the motor driver is connected must take care of the low-level, resource-consuming signal generation. Products in this category include the Pololu TreX Dual Controller and the JrK Motor Controller
Brushed DC motor controllers are DC motor drivers with additional intelligence: an on-board microcontroller generates the low-level signals and presents the user with higher-level interfaces and commands. The TB6612FNG Dual Motor Driver Carrier falls into this group of controllers
Stepper motor drivers are specifically designed to drive stepper motors, which are capable of continuous rotation with precise position control, even without a feedback system. Our stepper motor drivers include the Pololu A4988 Stepper Motor Driver Carriers, Sparkfun EasyDriver and Big Easydriver Stepper Motor Drivers
