Using a 4 axis 2 stepper motor driver with arduino

So, I recently got my 4 Axis 2 Phase Stepper Motor Driver 4A16 from aliexpress and I want to connect it to my arduino so i can use it to control 4 steppers, can't find anything on the internet about how to wire it up...
Any help is much appreciated

The link claims they will send you a product manual.

Did you leave an email address for them to forward the manual to? Personally I’d have asked for that
first and not ordered till I had seen it.

You should have demanded the manual first before buying.
