5pcs DRV8825 Stepper Motor Driver Module for 3D Printer Reprap RP A4988,Default NO

Product 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
