Product description: JRK G2 24v21 - single channel USB motor controller with feedback 40 V / 21 A - Pololu 3149

Extremely simple motor controller with feedback support belonging to the second generation of JRK controllers - JRK G2. Provides easy speed or position control (but not for both simultaneously). Available communication interfaces: USB, TTL, I2C, analog and radio. Supply voltage is from 6.5 V to 40 V and continuous current up to 21 A.

Technical specification of the controller

  • Supply voltage for motors: from 6.5 V to 40 V
  • Continuous current per channel: 21 A
  • Maximum PWM signal frequency: 20 kHz
  • Number of channels: 1
  • Connector: microUSB
  • Interfaces: USB, serial TTL, I2C, RC servo, analog voltage
  • Protection against reverse connection of power supply
  • Dimensions (without connectors): 43 x 30 x 11 mm
  • Weight ( without connectors): 10 g

The kit requires simple soldering of basic electronic components.

Special features JRK G2 24v21

  • Easy open or closed loop control of one DC motor
  • 5 control interfaces
    • USB: direct connection to the computer
    • Serial TTL: works with 5 V, for connection to a microcontroller
    • I2C: for connection to microcontroller
    • Radio signal for connection to RC system
    • Analog voltage for use with a potentiometer or pad
  • Feedback options
    • Analog voltage; 0 V to 5 V - for closed loop system
    • Frequency: for speed control using pulse counting
    • None: for open loop
    • (the controller does not support quadrature encoders)
  • 20 kHz ultrasonic PWM - silent operation (5 kHz can also be set)
  • Simple control and calibration using dedicated software
  • Configurable:
    • PID coefficients
    • Maximum current
    • Maximum PWM signal filling
    • Maximum acceleration and deceleration
    • Fault response
    • Input calibration for analogue and RC control
  • CRC error detection
  • Reverse polarity protection
  • Firmware upgradeable

Comparison of JRK with the new generation - JRK G2

The new G2 family has many improvements over the older JRKs. The JRK G2 drivers support higher operating voltages and higher currents, yet are smaller than their predecessors. Other features:

  • Hardware current limiting - the controller limits the motor current if it exceeds a set threshold
  • More accurate speed control at low frequencies
  • I2C interface for increased controllability
  • Possibility to measure VIN voltage to monitor power supply or batteries
  • MicroUSB connector instead of miniUSB
  • Speed reduction limitation (JRK first version had only acceleration limitation)
  • PID coefficients can be changed live via UART, I2C or USB

The JRK G2 controllers are software compatible with the older version, so there is no need to replace the control application.
