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 our free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC). This version offers a wide 6.5 V to 30 V operating range and can deliver continuous output currents up to 19 A without a heat sink. Male headers and terminal blocks are included but not soldered, allowing for custom installations.

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).

Notes:

1

Without included hardware.

2

Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 24 V, which leaves a safety margin for ripple voltage on the supply line. Not recommended for use with 24V batteries.

Typical results at room temperature running at 90% duty cycle.
