8Pcs DRV8825 Stepper Motor Driver Module with Heat Sink for 3D Printer RepRap 4 RAMPS1.4 StepStick A4988

Description

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 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 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) Package include: 8 x DRV8825 stepper motor driver module

Features

• The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver.
• 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).
• The DRV8825 module has a pinout 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.
• Six different steps resolutions: full step, half step, 1/4-step1/8-step1/16-step, 1/32-step, interface directly with 3.3 V and 5 V systems, 4 Layer 2 oz copper PCB, in order to improve heat dissipation
• DRV8825 stepper motor driver module adjustable current control lets you set a potentiometer, which lets you use the stepper motor's rated voltage or more, in order to achieve a higher rate of maximum output current step
