DRV8825 Stepper Motor Driver with Aluminum Heat Sink

DRV8825 Stepper Motor Driver with Aluminum Heat Sink

This product is a breakout board for the DRV8825 micro stepping bipolar stepper motor driver from TI. It can control a bipolar stepper motor with adjustable current limiting, overcurrent, and overtemperature protection, and six micro step resolutions (up to 1/32-step). It works with 8.2 – 45 V power supply and can deliver up to about 1.5 A per phase without cooling (up to 2.2 A per phase with adequate cooling). It has a similar pinout and interface as the A4988 stepper motor driver carriers, so it can replace them in many applications with better performance.

The board comes with an aluminum heat sink for better heat dissipation.

Features

This text describes the features of a stepper motor driver. Here is a possible rewrite:- You can control the stepper motor with simple step and direction signals.
– You can choose from six step resolutions: full, 1/2, 1/4, 1/8, 1/16, or 1/32.
– You can adjust the maximum current output with a potentiometer. This allows you to use higher voltages than the rated voltage of the stepper motor and achieve faster step rates.
– The driver automatically selects the best current decay mode (fast or slow) for optimal performance.
– The driver can handle up to 45 V of supply voltage.
– The driver has a built-in regulator and can work with 3.3 V or 5 V systems directly.
– The driver has protection features such as thermal shutdown, over-current shutdown, under-voltage lockout, short-to-ground and shorted-load detection.
– The driver has a 4-layer, 2 oz. copper PCB for better heat dissipation.
– The driver has an exposed solderable ground pad on the bottom of the PCB under the driver IC.
