Help connecting my BTS7960 Arduino board to a servo motor

Hi, my knowledge with this is very limited and it is the first time I am using this board.
I have an Arduino BTS7960 43A stepper motor drive.
I want to control the steering of a power wheels car by remote control and I am using a wiper motor as a servo.
I connected the board with 12V B+ B-
I connected my motor to M+ M-
And from the steering servo connected to my receiver unit I have two wires with 5V (5V+ 5V-) that I want to connect to my Arduino board in order to activate my motor forth ward and reverse but I don’t know what pins to use. I have tried all of them with no results.
Any help will be greatly appreciated. Thank you very much.

Welcome to the Forum
The output from your receiver will be a pulse signal for a servo unit.
The stepper motor driver you have is not a servo and probably needs a different type of input.
Arduino in the name of the driver means it is suitable for connection to arduino controllers.

You will need to have a programmed arduino between your receiver and stepper driver to accomplish what you need.

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Can you please post a picture of your project?

Also links to the stepper motor driver spec/data.

Thank you very much for helping me.
I am attaching a picture, I hope that they make sense.

I have to try again, since my picture was too large.
Sorry for the inconvenience.


Before you do anything more, put a fuse in line with the positive battery lead and an ON/OFF switch.

At the moment you will be tempted to make wiring changes with 12V connected, and Lead Acid Batteries are not kind when presented with shorts, or poor connections.

Thank you for your advise. I’ll do that now.
I’ll keep checking this forum for further advise for my project. If there’s anything else I can provide, please let me know.
