The Pololu Roboclaw Solo 30A Motor Controller with DC-Motor Driver, RC, TTL, USB, Analog is a high-power motor controller for continuously operating DC motors. It is capable of driving up to 30A of continuous current, and up to 34V of input voltage. The controller can be interfaced over RC, TTL, USB, and analog signal lines, allowing it to work with a wide variety of host systems. This controller can be used to provide a simple current-limit for brushed motors, or to implement complex microstepping for stepper motors. Additionally, it contains multiple cutting-edge safety features, such as over-voltage and over-current protection.
