The ISD04 is a parallel port control series of miniature high performance stepper motor drivers.Its biggest feature is its small size and strong driving ability.Its thickness is less than 14 mm.They can be directly mounted onto NEMA 17, 23, 24 series stepper motors with the corresponding flange.ISD04 can provide 1.5 - 4A adjustable peak current.Its high-speed current compensation function can compensate for the effects of back electromotive force when the motor rotates at high speed.
