About 2Pack DRV8825 Stepstick Stepper Motor Driver Module

The DRV8825 stepper motor driver carrier is a breakout board for TI's 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 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 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:Simple step and direction control interfaceSix different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-stepAdjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor rated voltage to achieve higher step rates45 V maximum supply voltageBuilt-in regulator (no external logic voltage supply needed)Can interface directly with 3.3 V and 5 V systemsOver-temperature thermal shutdown, over-current shutdown, and under-voltage lockoutShort-to-ground and shorted-load protection4-layer, 2 oz copper PCB for improved heat dissipationExposed solderable ground pad below the driver IC on the bottom of the PCBModule size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects Package included:2 x DRV8825 Stepper Motor Driver Board2 x Heatsinks
