DRV8825 Stepper Motor Driver with Heat Sink

DRV8825 Stepper Motor Driver Module Six different step resolutions for 3D Printer RepRap 4 RAMPS1.4 StepStick DRV8825 Stepper Motor Driver Module: With over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout function. More stable than A4988 module. Working Voltage: 8.2~45V Working Current: 2.5A (MAX) Support Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step. Support short circuit, overheat protection The DRV8825 stepper motor driver carrier is a breakout board for 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 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 overtemperature protection, and six microstep 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). Features: 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 rated voltage to achieve higher step rates 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 4-layer, 2 oz copper PCB for improved heat dissipation Exposed solderable ground pad below the driver IC on the bottom of the PC
