DRV8825 Stepper Driver

 
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.
These drivers come with the headers already soldered – making them truly plug-and-play with any CNC Shield or  RAMPS board.
 
They also come complete with a small heatsink chip, with adhesive already attached.
