DRV8825 Motor Driver Module: Pinout, Datasheet, Application [Video]

The DRV8825 Motor Driver Module is a driver with two H-bridge drives and a microstepping indexer. The driver has a maximum output capacity of 45 V and ± 2.5 A. It can operate bipolar stepper motors in full, 1/2, 1/4, 1/8, 1/16 and 1/32-step modes. This driver module is generally used in Robotics, ATMs and Gaming Machines.

This is a tutorial video showing how to control stepper motor driver with DRV8825 Module.

How to Use DRV8825 Driver Module

The interface diagram for DRV8825 is shown below. You can control the stepper motor with very few pins using the DRV8825. The module has a pinout and interface that are almost identical to those of the A4988 stepper motor driver carrier.

DRV8255 Schematic Diagram

As shown in the diagram above, the module pins DIR, STEP and FAULT are connected to the microcontroller to drive the stepper motor. STEP pin used to control steps while the DIR pin is used to control directions. The DRV8825 also features an FAULT pin, the Fault pin is shortened to the SLEEP pin, so whenever the Fault pin is low, the whole chip is disabled. Microstep pins (M0, M1 and M2) are used to operate the driver module in a variety of step functions. In the above circuit M0, M1, and M2 pins left off, this means that the driver will operate in full-step mode. DRV8825 has low-ESR ceramic capacitors on board, making it vulnerable to voltage spikes.

Therefore, it is recommended to put an at least 47µf capacitor across the motor power supply pins. It is commonly used in controlling the NEMA series stepper motors like NEMA17, NEMA23, NEMA34.
