The 3d Printer Stepstick Drv8825 Stepper Motor Driver carrier is an expansion board for the DRV8825 micro stepping bipolar stepper motor driver from Texas Instruments. Because the module’s pinout and interface are substantially identical to those of our A4988 stepper motor driver carriers, it can be used in many applications as a higher-performance drop-in replacement for those boards. The DRV8825 has six microstep resolutions (down to 1/32-step) and configurable current limiting. It also has over current and over temperature safety. It can produce up to 1.5 A per phase without a heat sink or forced air flow and operates between 8.2 and 45 V. (rated for up to 2.2 A per coil with sufficient additional cooling).
