         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:      
    MODE0 MODE1 MODE2 Microstep Resolution
    Low Low Low Full step
    High Low Low Half step
    Low High Low 1/4 step
    High High Low 1/8 step
    Low Low High 1/16 step
    High Low High 1/32 step
    Low High High 1/32 step
    High High High 1/32 step
        There are 2 wiring modes for connecting a microcontroller to the DRV8825 module:




    • 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
    • Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor?s rated voltage to achieve higher step rates
    • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
    • 45 V maximum supply voltage
    • Built-in regulator (no external logic voltage supply needed)
    • Can interface directly with 3.3 V and 5 V systems
    • Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
    • Short-to-ground and shorted-load protection
