Product Description

Overview

With integrated support for analog voltage or tachometer (frequency) feedback, the second-generation G2 family of Jrk motor controllers makes it easy to add closed-loop control of speed or position (but not both!) of a single brushed DC motor to a variety of projects. These versatile, general-purpose modules support five different control interfaces: USB for direct connection to a computer, TTL serial and I²C for use with a microcontroller, RC hobby servo pulses for use in an RC system, and analog voltages for use with a potentiometer or analog joystick. They also offer many settings that can be configured using our free configuration software utility for Windows, Linux, and macOS. This software simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB (a micro-B USB cable is required to connect the Jrk G2 to a computer).

Main 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
Arduino library makes it easy to get started using these controllers with an Arduino or compatible board
Comprehensive user’s guide

The Jrk G2 24v21 operates from 6.5 V to 40 V and can deliver a continuous output current of 21 A without a heat sink. Note that 40 V is the absolute maximum for this controller; the maximum recommended operating voltage is 34 V, and the maximum recommended nominal battery voltage is 28 V.

If you need to identify which version you have, you can just plug it into a computer through USB and the Jrk software will tell you. For quick visual identification without a computer, you can distinguish this version from the identically sized Jrk G2 18v27 by the number 100 on top of the tall silver electrolytic capacitors.

Identifying markings

PCB dev codes:umc04a
Other PCB markings:0J10858, blank white box

Notes:

1/Without included hardware.
2.Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 34 V, which leaves a safety margin for ripple voltage on the supply line.
3.Typical results at room temperature running at 90% duty cycle.
