DRV8825 Stepper Motor Driver with Aluminum Heat Sink

DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil.

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)

45V maximum supply voltage

Built-in regulator (no external logic voltage supply needed)

Can interface directly with 3.3V and 5V 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
