@Nca78 Thank you so much for your time, i didn't use the stepper motor yet and so i didn't pay attention to what came with it, thank you very much.

i got it as a bonus item from a kit i bought but there is nothing that could tell me what it is, I am new to Arduino and electronics, and i was planning to use every sensor that i got from the kit at least once and learn about it but this unknown Hardware is ruining my plans as it is the last thing i have to test and learn about.
all i found about it on the internet is this picture and nothing else, got no name or anything useful to know what it is.
