HALJIA StepStick DRV8825 Stepper Motor Driver Carrier Reprap 4 layer PCB with Heat Sink Compatible 3D Printer RP A4988

Simple step and direction control interface. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step The module 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. The DRV8825 features adjustable current limiting, over-current and over-temperature protection, and six micro step resolutions (down to 1/32-step). It operates from 8.2 ¨C 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).
