I just tried to connect a 2 Amp stepper motor to ULN2003, and yes, it did fry. Any suggestions on other chips that might handle this amount of current? And info about wiring also. I´m also worried that I blew my motor. Do you have any easy and fast tips on how to chech if it is dead? Thanks!

How about a SPP04N80C3
It has a gate turn on of 3.9V max
It has a whopping voltage and big current:-
