Pololu Simple Motor Controllers

Simple motor controllers provide straightforward, reliable control of brushed DC motors in a wide range of robotics, automation and embedded projects. They accept a variety of input signals – USB, TTL serial, analogue voltage from a potentiometer, hobby‑radio PWM and, on newer versions, I²C – allowing easy integration with microcontrollers, development boards or remote‑control systems. Configuration is handled through free PC‑based software that connects via USB, so parameters such as speed limits, acceleration ramps and current protection can be tuned without soldering.

Different models cover power levels from low‑voltage hobby use up to high‑power applications, offering built‑in protection and robust heat dissipation. The combination of multiple interfaces, configurable firmware and solid current handling makes these controllers a practical choice when precise, repeatable motor control is required.
