HiLetgo 5pcs DRV8825 Stepper Motor Driver Module for 3D Printer RepRap 4 RAMPS1.4 StepStick

Description: The DRV8825 stepper motor driver carrier is a breakout board for DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, 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 ¨C 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 rated voltage to achieve higher step rates * 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) Package included: 5pcs DRV8825 Stepper Motor Driver Board.
