[3DMakerWorld] Pololu DRV8825 High Current Stepper Motor Driver Carrier

Description

Key Features:
Simple step and direction control interface
Adjustable current control lets you set the maximum current output with a potentiometer
Built-in regulator (no external logic voltage supply needed)
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
Short-to-ground and shorted-load protection
This breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 V to 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 driver 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.
