    Product Description

    Package includes

    1x High Current DRV8825 Stepper Driver For Nema17 Stepper Motor

    1x Heatsink

    Overview

     

    The DRV8825 stepper motor driver carrier 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 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 

    • 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, which 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
    • Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)
