This powerful motor controller makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using the free software. It supports five control interfaces: USB, TTL serial, I2C, analogue voltage (potentiometer), and hobby radio control (RC). This version offers a wide 6.5 V to 40 V operating range and can deliver continuous output currents up to 13A without a heat sink.

General Specs:

  • Motor Channels: 1
  • Control Interface: USB, non-inverted TTL serial, I2C, RC servo pulses and an analogue voltage
  • Minimum Operating Voltage: 6.5V
  • Maximum Operating Voltage: 40V
  • Continuous Output Current per Channel: 13A
  • Max PWM Frequency: 20 kHz
  • Reverse Voltage Protection: Yes
  • Version: G2 27v13 (40V max, 13A max continuous)

Features of the Jrk G2 family:

  • Easy open-loop or closed-loop control of one brushed DC motor
  • A variety of control interfaces:
    • USB for direct connection to a computer
    • TTL serial operating at 5 V for use with a microcontroller
    • I²C for use with a microcontroller
    • RC hobby servo pulses for use in an RC system
    • Analog voltage for use with a potentiometer or analog joystick
  • Feedback options:
    • Analog voltage (0 V to 5 V), for making a closed-loop servo system
    • Frequency, for closed-loop speed control using pulse counting (for higher-frequency feedback) or pulse timing (for lower-frequency feedback)
    • None, for open-loop speed control
    • Note: the Jrk does not support using quadrature encoders for position control
  • Ultrasonic 20 kHz PWM for quieter operation (can be configured to use 5 kHz instead)
  • Simple configuration and calibration over USB with free configuration software utility (for Windows, Linux, and macOS)
  • Configurable parameters include:
    • PID period and PID coefficients (feedback tuning parameters)
    • Maximum current
    • Maximum duty cycle
    • Maximum acceleration and deceleration
    • 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
