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
-
