Photo 5pcs StepStick Pololu stepper driver A4983 A4988 DRV8825 for Ramps1.4 3D printer The DRV8825 stepper motor driver carrier is a breakout board for TI's 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 – 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). 1)Simple step and direction control interface2)Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step 3)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 4)45 V maximum supply voltage 5)Built-in regulator (no external logic voltage supply needed) 6)Can interface directly with 3.3 V and 5 V systems 7)Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout 8)Short-to-ground and shorted-load protection 9)4-layer, 2 oz copper PCB for improved heat dissipation 10)Exposed solderable ground pad below the driver IC on the bottom of the PCB 11)Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information) Package List 5 x DRV8825 stepper motor driver Payment We accept paypal only.
