DRV8825 Stepper Motor Driver with Aluminum Heat Sink

Description

The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 micro stepping bipolar stepper motor driver.
The DRV8825 features adjustable current limiting, over current and over temperature protection, and six micro step 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).
The module has a pin out and interface that are nearly identical to those of our A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.

Features:
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
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
Module size, pin out, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motors 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)
