Specification

Description

The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of the A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.

The DRV8825 Motor Driver features adjustable current limiting, overcurrent, and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

Features :

Microstepping Capability: Supports up to 1/32 micro-stepping, providing smooth motor control and improved precision.

Adjustable Current Control: Allows setting a maximum current output to the stepper motor, which can be adjusted using a small potentiometer. This helps prevent overheating of the stepper motors and increases their longevity.

Over-temperature Protection: Built-in protection against over-temperature, ensuring the driver shuts down when overheated, preventing damage.

Applications:

CNC Machines: The DRV8825 is commonly used to drive stepper motors in CNC routers, laser cutters, and engraving machines. The fine-tuned control offered by the micro-stepping feature ensures smooth and accurate movement of the tool head.

Robotics and Automation: Robotic Arm Control: In robotics, DRV8825 is used to control the precise movement of stepper motors for robotic arms and other automated mechanisms.

Features:

  • DRV8825 stepper motor driver module
  • 45V maximum supply voltage
  • 4 layer, 2 oz copper PCB for better heat dissipation
  • Can directly interface with 3.3V and 5V systems
  • Simple step and direction control interface

Using the Driver

Integration with Arduino


Sample Code

Additional Details

  • Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
  • Simple step and direction control interface
  • Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
  • Adjustable current control lets you set the maximum current output with a potentiometer. Hence lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
  • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
  • 45 V maximum supply voltage
  • Built-in regulator (no external logic voltage supply needed)
  • Can interface directly with 3.3 V and 5 V systems
  • Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
  • Short-to-ground and shorted-load protection
  • 4-layer, 2 oz copper PCB for improved heat dissipation
  • Exposed solderable ground pad below the driver IC on the bottom of the PCB
