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 module
, 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 and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 ? 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow.
DRV8825 allows higher resolutions by allowing intermediate step locations, which are achieved by energizing the coils with intermediate current levels. The resolution (step size) selector inputs (MODE0, MODE1, and MODE2) enable selection from the six step resolutions according to the table below:
There are 2 wiring modes for connecting a microcontroller to the DRV8825 module:
