Pololu 1394 Jrk 21v3 USB Motor Controller with Feedback (Fully Assembled)

The Jrk 21v3 is a versatile, general-purpose motor controller that supports a variety of interfaces, including USB. The broad operating range from 5 V to 28 V and continuous output current of 3 A (5 A peak) allow this board to control most small DC brushed motors. Analog voltage and tachometer (frequency) feedback options allow quick implementation of closed-loop servo systems, and a free configuration utility (for Windows) allows easy calibration and configuration through the USB port. A USB A to mini-B cable (not included) is required to connect this controller to a computer.

Key improvements over competing products and earlier Pololu motor controllers with feedback include:

  • USB connectivity with emulated serial (COM) port allows direct motor control from a PC
  • Ultrasonic PWM to eliminate switching-induced motor shaft hum or whine
  • Robust, high-speed communication protocol with user-configurable error condition response
  • High internal resolution (12 bits) for smooth and flexible calibration to various input and feedback devices
  • Current sensing and limiting
  • Reversed power protection
  • Field-upgradeable firmware

  1. 5 out of 5

    Pololu's JRK controllers are amazing with huge power from a tiny board. Very fine control using a joystick and ability to program it via its own USB connector make this a remarkable motor control board.It's also bulletproof as I've discovered!!Thoro
