These motor controllers allow variable speed and direction control of two brushed DC motors using a simple serial interface, making it easy to add motors to your microcontroller- or computer-based project.
The TReX blends RC, analog, and serial inputs for a powerful motor control solution. The TReX will work right out of the box as an electronic speed control (ESC), but its ability to seamlessly transition between RC/analog and serial control makes it capable of so much more!
The Pololu Simple Motor Controllers make basic control of brushed DC motors easy. Our most versatile and configurable motor controllers yet span a wide range of power levels and offer four interface modes: USB, TTL serial, analog voltage, and hobby radio control (RC).
The jrk motor controllers are highly configurable brushed DC motor controllers that can be used as an open-loop speed control or for closed-loop speed or position control. They support four interface modes: USB, TTL serial, analog voltage, and hobby radio control (RC).
The RoboClaw motor controllers from Ion Motion Control (formerly Orion Robotics) can control a one or two brushed DC motors using USB serial, TTL serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system, or analog feedback can be used for position control.
