This is a bulk-packaged version of the DRV8825 Stepper Motor Driver Carrier that ships with 0.1″-pitch male header pins installed as shown in the main product picture, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard.

DRV8825 Stepper Motor Driver Carrier: 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. This board ships with 0.1″ male header pins included but not soldered in.
