The Pololu Simple Motor Controllers (SMCs) 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 a variety of interface modes, including USB, TTL serial, analog voltage, and hobby radio control (RC).
The RoboClaw motor controllers from Basicmicro (formerly Ion Motion Control) 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.
The powerful MCP motor controllers from Basicmicro (formerly Ion Motion Control) can control a pair of brushed DC motors using USB serial, TTL serial, RS-232 serial, CAN bus, RC, or analog inputs. They include integrated dual quadrature decoders and advanced features including internal scripting support and user-configurable I/O.
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!
