comprei o shield cnc v4 pro o arduino nano, ele veio com o drive A4988, gostaria de fazer uns testes com motrores que ja tenho no caso o motor de passo 28BYJ-48 nele eu uso o drive ULN2003, ja vi que por o motor ser unipolar o Drive A4988 não serve, gostaria de saber se com o ULN2003 consigo ligar no CNC shield
