Please help me connect it correctly!

I found a scheme on this site, put it together, but nothing works(How do I connect it so that the engine works?

Hello.

I moved your post to the motor controllers support category since that is a better place for it.

We do not have any connection diagrams for our Simple Motor Controllers that look like that, so I am not sure what this is referring to. Can you post a link to where you found that diagram? If there is a version of the site in English that you can link to, that would be ideal.

Can you also post some pictures of the actual motor controller you are using, including close-up pictures of both the top and bottom sides of the board?
