My team and I have recently ordered the Stepper Motor Controller: " Stepper Motor Driver, DROK DC-DC Stepping Motor Module 5-30V 9V 12V 24V V3 Dual H-Bridge 4-Channel 2A Step Motor Driver Controller Board Chip with USB Port "…
This board is a duel h-bridge version of the motor controller: L298N
We also have 2 stepping motors (of type: Nema 17) which we want to connect to the controller in order to power and control the motors.
However, there is very limited information online with regards to which pins we connect each of the stepper motors wires (A+/A- & B+/B-) for each motor to this specific motor controller board.
The amazon link  shows the amazon link with images that describe and specify the different ports of the board.
The  link gives an explanation to how to connect the stepper motor to a singular h-bridge controller (L298N) including all the relevant port connections.
Questions we want to ask:
Have you had any experience with this board?
Have you ever had access to the specific datasheet for this particular board?
Do you have any advice to how we should approach the problem?
If we go ahead and test the stepper motor wires on the board, if we get these wires wrong, is there a chance either the board or the stepper motors themselves will get fried/damaged?
Thank you in advanced!
