Product Description

Overview

This compact motor controller makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using our free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC). This version offers a 4.5 V to 28 V operating range and can deliver continuous output currents up to 2.6 A (5 A peak) without a heat sink. Male headers and terminal blocks are included but not soldered, allowing for custom installations.

The Jrk G2 21v3 operates from 4.5 V to 28 V and can deliver a continuous output current of 2.6 A (5 A peak) without a heat sink. The controller supports transient operation (< 500 ms) up to 40 V, and the maximum recommended nominal battery voltage is 24 V. This version has header pins and terminal blocks included but not soldered, so soldering is required to use it.

A version is also available that requires no soldering to use as the terminal blocks and main header pins are already installed.(PO3143)

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

Identifying markings

PCB dev codes:umc06a
Other PCB markings:0J11316

Notes:

1.Without included hardware.
2.Powering the Jrk G2 21v3 with a supply voltage between 4.5 V and 5.5 V might cause its logic voltage to be lower than normal, which could affect operation. See the user’s guide for more information.
3.Transient operation (< 500 ms) up to 40 V.
4.Typical results at room temperature running at 90% duty cycle with VIN > 8 V. Operation from 4.5 V to 8 V reduces maximum current output.
