Pololu USB/RC/TTL/Analog motor controller with feedback 12A bidirectional control of a brushed DC motor

The Polulu USB/TTL/Analog Motor Controller with Feedback 12 A is the versatile and general purpose Jrk 12v12 USB Motor Controller that supports USB, TTL, Analog Voltage and RC radio control interfaces.

The application range from 6 to 16 V and a high continuous output current of 12 A (peak value at 30 A) allow the motor controller with feedback to control many medium-sized DC motors.

Feedback options for analog voltage and tachometer (frequency) allow fast implementation of control loop systems. In addition, a free configuration utility (for Windows XP or Vista) allows easy calibration and configuration due to the USB port.

Decisive improvements over competing products and older Polulu motor controllers include the following:
• USB connection with emulated serial (COM) port allows direct motor control from PC.
• Ultrasonic PWM to eliminate circuit induced humming or howling of the motor shaft.
• Robust, high-speed communication protocol with user-configurable error state reaction
• High internal resolution (12 bits) for smooth and flexible calibration of various input and feedback devices
• sampling and limitation of current intensity
• Rücc power protection
• Range expandable firmware
