| Aug 30, 2021 at 23:09 | comment | added | Franva | thanks a lot @Neil_UK finally someone listened and explained why that motor controller can do it whereas mine cannot. Yep, will try to get a module of 6612. | |

@Franva I quote This little chip can drive either two DC motors or one stepper motor. It's designed to drive DC motors as well as steppers. The board you linked to is only designed to drive steppers, which means it has helpful extra stuff in there that makes it either difficult or impossible to drive plain DC motors. Besides, the one you linked to has a minimum voltage of 8.5 V, so your battery does not have the voltage anyway. The 6612 looks a nice product, use it.

In which section, there is a link to a article which teaches how to use Stepper Motor Controller(SMC) to control DC motors. Could you please explain why he can do it with SMC and why I cannot do the same?? | |

| Aug 29, 2021 at 14:43 | comment | added | Neil_UK | @Franva The T825 has a minimum input voltage of 8.5 V. It's also a stepper motor controller, which is the wrong thing to use for a PMDC motor. Rather like trying to write a novel with a badminton raquet - you could probably make it work by tying a pencil on the end, but it's not the right thing to use. | |

| Aug 29, 2021 at 14:10 | comment | added | Transistor | @Franva, Niel and others have explained that you have the wrong controller for those motors. "I want to make carrot soup. I've bought cucumbers." Can you see the problem? | |
| Aug 29, 2021 at 12:58 | comment | added | Franva | Hi @Neil_UL, the stepper motor controller I used is Polulu Tic T825(pololu.com/product/3131/specs) I don't know what's the voltage it outputs. But the car battery as you can see from the image is 7.4V, so will the stepper motor controller provide enough voltage to the 2 motors? | |
