DAOKI 5Pcs DRV8825 3D Stepper Motor Drivers Module for 3D Printer RepRap StepStick for Arduino with Heat Sink Carrier

Description: 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 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 4-layer, 2oz. copper PCB for improved heat dissipation Exposed solder able ground pad below the driver IC on the bottom of the PCB 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) Package Included: 5 x Arduino DRV8825 stepper motor driver Module 3D printer RAMPS1.4 RepRap StepStick 5 x Heatsinks
