3X DRV8825 Stepper Motor Driver Module RepRap 3D Printer StepStick RAMPS CNC

Each module comes witha 9mm x 9mm x 5mm heat sink with 3M Thermally Conductive Interface Tape foreasy mounting.

This product is a carrier board or breakout board for TI’sDRV8825 stepper motor driver; we therefore recommend careful reading of theDRV8825 datasheet before using this product. This stepper motor driver lets youcontrol one bipolar stepper motor at up to 2.2 A output current per coil (seethe Power Dissipation Considerations section below for more information).

Here are some of the driver’s key features:

• Maximum current per phase: 2.2 A (w/ sufficient cooling)
• 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 currentoutput with a potentiometer, which lets you use voltages above your steppermotor’s rated voltage to achieve higher step rates
• Intelligent chopping control that automatically selects thecorrect 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, 2 oz. copper PCB for improved heat dissipation
• Exposed solderable ground pad below the driver IC on thebottom of the PCB
• Module size, pinout, and interface match those of our A4988stepper motor driver carriers in most respects (see the bottom of this page formore information)
