Description: The DRV8825 stepper motor driver carrier is a breakout board for TIs DRV8825 micro-stepping bipolar stepper motor driver. The module has a pin-out 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 8.2~45 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). Features: 1. Simple step and direction control interface 2. Six different step resolutions: full-step half-step 1/4-step 1/8-step 1/16-step and 1/32-step 3. Can interface directly with 3.3V and 5V systems. 4. Over-temperature thermal shutdown over-current shutdown and under-voltage lockout 5. Short-to-ground and shorted-load protection 6. 4-layer 2 oz copper PCB for improved heat dissipation 7. The bottom of the PCB can be exposed solderable ground pad below the driver IC 8. Module size pin-out and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information) 9. Adjustable current control lets you set the maximum current output with a potentiometer which lets you use voltages above your stepper motors rated voltage to achieve higher step rates 10. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) 11. Maximum 45V voltage supply 12. Built-in regulator (no external logic voltage supply needed)
