UIM24302 Stepper Motor Controller is a miniature, high performance stepper motor controller. They can be mounted onto NEMA 17 / 23 series stepper motor seamlessly through corresponding flanges. The thickness of these controllers is less than 14 mm.

After properly adjusting/setting the speed and direction, it can run the motor on power up without the need of user control device. It is a good replacement of a servo system in applications need low cost but not hyper accuracy.

UIM24302 is capable to provide 0-2A adjustable phase current. Their mixed-decay current control reduces the back-EMF effect under high motor speed and improves the performance. Except that UIM24302 takes 10-35VDC input. Enclosure is made of die-cast aluminum which provides a rugged durable protection and improves the heat dissipation.

Further more stepper drive with parallel port and RS232 stepper controller and stepper controller with Canbus are available.
