Description

Use to replace the A4988 to upgrade your 3D printer.

Feature

– Simple step and direction control interface

– 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 solder-able ground pad below the driver IC on the bottom of the PCB

– 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)

– Module size, pinout, and interface match those of our A4988 stepper motor drivers

Package includes:

5 x DRV8825 Stepper Motor Driver Module

5 x Heat Sink
