DRV8825 Stepper Motor Driver Module

The DRV8825 Stepper Motor Driver Module is an excellent motor driver solution for printers, scanners and automated equipment applications, and is often used by our customers for the 3D Printers we sell. The driver block consists of N-channel power MOSFET’s set to full H-bridge to drive motors at 24V with up to 2.5A on each of the channels via two H-bridge drivers and a microstepping indexer – originally intended for bipolar Stepper Motors.

This driver offers an easy STEP-DIR interface for simple controller circuit interfacing, as well as physical mode pins to configure the motor microstepping modes between full-step and 1/32-step. The driver unit also features multiple decay modes, configurable to slow decay, fast decay or mixed decay mode.

Additionally, these Stepper Motor Drivers offer protection features to safeguard from overcurrent, short circuits, undervoltage, as well as high temperatures. And to add some extra functionality and make your life easier, it has an nFAULT pin that indicates if there is a fault, so you can quickly identify a problem and fix it before it becomes costly.

Please note that this unit does include a heatsink, as this is required in order to push the driver up to its full 24V capabilities.

Typical Applications for the DRV8825 Stepper Motor Driver Module:

Although we typically stock the DRV8825 Stepper Motor Driver Module as a replacement for the A4988 stepper motor driver, this unit can be used for almost any application in which basic stepper motors are used. This includes standard machines like scanners, printers and common automation, but also includes some more exciting applications such as:

• Building a money-counting or handling machine that uses highly precise microstepping to ensure optimal accuracy for quick and efficient cash transfers.
• Creating gaming machines that react in various ways to inputs like joysticks or basic coin insertions.
• Integrating automatic or manual control into security cameras to ensure that each camera can scan the area and reach every corner of a home, office or other location.

These Stepper Motor Drivers are great investments for anyone interested in automation or precise motor control applications, which is why we always recommend these for our customers who need replacement parts for 3D Printers. With a 2.5A current supply over each channel at 24V, this driver can be used for a wide range of different light to moderate power applications.
