DRV8825 Stepper Motor Driver with Aluminum Heat SinkThis breakout board for Texas Instruments' DRV8825 micro stepping bipolar stepper motor driver includes adjustable current limiting, over current and over temperature protection, and six micro step resolutions (down to 1 32 step). It can deliver up to 1. 5 A per phase without a heat sink or forced airflow and operates from 8. 2 V to 45 V. (rated for up to 2. 2 A per coil with sufficient additional cooling) The pinout and interface of the driver are
