    The product looks good! I tried with a 4 wire stepper motor and its works fine. I'd like to reprogramming the board and using 5 wire steppers but i cant find the "program" what i should download!! No attached connection diagram,instruction,manual etc.!! How can i using the trim pot? If i connecting the three terminals to the board ( as visible on the picture at product page) I'll make damage!! Because the first pin on 5V+ the middle is on ground and the third one is the signal. It can be make a short circuit and make a damage on the board and/or the trim pot!! I connected the middle cable of trim pot to the signal pin and the remaining two connected to the 5V+ and ground pins. Nothing happened. There is no reaction if i turn the trim pot.No rpm changing no smoke nothing.The stepper still runs at the same rpm.It possible to modifying the rpm with the buttons. I also tried with 2 normal motors as visible on the picture at product page. the motors are not spinning continuously at "high"rpm and they only shaking at "low" rpm adjustment. The power source and the rated voltage of motors was the same (5v)!! Some attachments ,downloadable info or instructions should be great!!
