The powerful jrk 12v12 motor controller with feedback is a highly configurable brushed DC motor controller that supports four interface modes: USB, logic-level serial, analog voltage, and hobby radio control (RC). The controller can be used as an open-loop speed control or for closed-loop speed or position control.

The jrk 12v12 is a versatile, general-purpose motor controller that supports a variety of interfaces, including USB. The 6 V to 16 V operating range and high continuous output current of 12 A (30 A peak) allow this board to control many medium-sized 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.

Key improvements over competing products 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

Features:

  • Simple bidirectional control of one DC brush motor
  • 6 V to 16 V operating supply range
  • 12 A maximum continuous current output (30 A peak)
  • Four communication or control options:
    • USB interface for direct connection to a PC
    • Full-duplex, TTL-level asynchronous serial interface for direct connection to microcontrollers or other embedded controllers
    • Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller
    • 0–5 V analog voltage interface for direct connection to potentiometers and analog joysticks
  • Two closed-loop feedback options:
    • 0–5 V analog voltage
    • Frequency/tachometer digital input up to 2 MHz with 1 ms PID period
    • Open-loop control with no feedback also available
  • Simple configuration and calibration over USB with free configuration program (Windows 8, Windows 7, Vista, and Windows XP compatible)
  • Configurable parameters include:
    • PID period and PID constants (feedback tuning parameters)
    • Maximum current
    • Maximum duty cycle
    • Maximum acceleration
    • Error response
    • Input calibration (learning) for analog and RC control
  • Optional CRC error detection eliminates communication errors caused by noise or software faults
  • Reversed power protection
  • Field-upgradeable firmware
  • Optional feedback potentiometer disconnect detection
