- Simplifies servo control of commonly available DC motors.
- three independent interfaces:
- a serial protocol for microcontroller-based applications,
- a pulse-width interface for connection to hobby radio control equipment or serial servo controllers, and an
- analog voltage interface for simple tests and demonstrations.
- closed-loop control of position or speed.
- A higher-power version, SMC04 high-power motor controller with feedback, is also available.
- bi-directional, closed-loop control.
How to use Pololu 3A Motor Controller with Feedback
- select either an analog voltage feedback or a digital encoder feedback.
- With the two feedback alternatives, various simple devices such as potentiometers can be used as sensors to achieve position or speed control.
- A feedback potentiometer is coupled to the mechanism output, and the user can then send position commands to the motor controller, which automatically drives the motor to reach the position.
- Alternatively, the mechanism and sensor can be arranged to provide speed feedback, in which case the motor controller maintains given speeds despite fluctuations in friction or supply voltage.
- measures 1.4" x 1.4" and has an operating voltage of 6–18 volts, best for small robots.
- multiple units to be connected to a single serial line to control a mixture of motors sizes and hobby RC servos.
