Tanotis Arduino DRV8825 stepper motor driver Module 3D printer RAMPS1.4 RepRap StepStick Remote Triggers It has 54 digital input/outputDescription This module is blue PCB now,please know it . The DRV8825 stepper motor driver carrier is a breakout board for TI's DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher performance drop in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, overcurrent
