Stepstick Pololu Stepper Driver DRV8825 for RepRap Ramps 1 4 Sanguinololu

Product Features Shanhai 4 Steps Step Pololu Stepper Drive DRV8825 for RepRap Ramp 1 4 Sanguinololu project instruction The DRV8825 stepper motor driver bay is a splitter for the TI DRV8825 Microstepping Stepper Motor Driver. The modules pinout and interface are nearly identical to our A4988 stepper motor driver board, so it can be used as a higher-performance plug-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 steps). It operates from 8.2 to 45 V and can deliver up to about 1.5 A per phase without the need for heat sinks or forced air flow (up to 2.2 A per coil with adequate extra cooling). 1) Simple step and direction control interface 2) 6 different step resolution: full step, half step, 1/4 step, 1/8 step, 1/16 step and 1/32 step 3) Adjustable current control allows you to set the maximum current output using a potentiometer, allowing you to use voltages higher than the stepper motor rated voltage for higher step rates 4) 45 V maximum supply voltage 5) Built-in regulator (no external logic voltage power supply) 6) Interface directly to 3.3V and 5V systems 7) over-temperature shutdown, over-current shutdown and under-voltage lockout 8) Ground short-circuit and short-circuit load protection 9) 4 layers of 2 ounce copper PCB, to improve heat dissipation 10) Exposing solderable ground pads underneath the driver ICs on the bottom of the PCB 11) In most respects, the module size, pinout and interface match our A4988 stepper motor driver bay packing list 4 x DRV8825 stepper motor driver
