Description of DROK Controller Regulator Industrial Optocoupler

DROK DC motor driver input voltage range is DC 6.5V-27V, can be input DC 12V or 24V, rated output current of each port is 7A, total output power is 160W. STRONG DRIVE: the motor controller board adopts dual H bridge, can drive two DC motors at the same time. FORWARD and REVSERSELY ROTATE: the IN1, IN2/IN3, IN4 port can control forward or reverse motor rotation. PWM SPEED CONTROL: enable signal terminal (ENA) input PWM can regulate speed, PWM frequency range 0-10KHZ. UNDER VOLTAGE PROTECTION: the motor driver module is with under voltage protection to prevent instantaneous large current from damaging the module.

Three stars are good for controller

Not intuitive board configuration. I lost several hours to get it working. Very little useful information on the web. The data sheet is almost illegible due to poor English. Drok technical support was slow and unhelpful. On most motor controllers, the +5V pin can be used as a power source for the microcontroller. On this board you actually need to provide a separate 5V power supply to the "+5V" and "GND" pins for the signal pins to work. I don't know why they couldn't have a built in buck…

Pros
  • controller
Cons
  • some little things

It doesn't work without PWM, but it works with it.

I'm completely rewriting my review on this thing. I use Raspberry Pi 3 to control the board. Here are some points to keep in mind when using this board: 1. I applied 5v and ground from my PI3 to the board's control pins as instructed. This activates the power display for the control pins and sets all control pins to just under 5V or HIGH. It wasn't clear at first, but after figuring it out I was able to adapt my program to work with it.2. I can activate motor 1 without any problems I can…

  • Controls and Indicators

  • Not sure

Impeccable performance. Highly recommended! Here's some help to get you started

This unit is perfect for my application with a pair of 2-3A DC motors and is way more than it's cost. I need frequent changes of direction and large transients, but the board stays cool and doesn't need a heatsink. The connectors have screw terminals and detachable snap connectors which are excellent. The documentation looks fine on glossy paper but needs some clarification. Here are some tips and an Arduino test setup: 1) This dual H-bridge can drive two motors independently. Miscellaneous. 2)

Pros
  • Motor Speed Controller
