USED FOR 3D OR CNC BOARDS. 1,5A PER PHASE. 6 STEP RESOLUTIONS. SEE ALSO ACM RAMPS STEPPER DRIVER DRV8825 Discontinued Specifications, Prices & Availability may change without notice. Images are for illustration purposes only. E&OE Overview 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 module, 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. DRV8825 allows higher resolutions by allowing intermediate step locations, which are achieved by energizing the coils with intermediate current levels. Features The resolution (step size) selector inputs (MODE0, MODE1, and MODE2) enable selection from the six step resolutions according to the table below: MODE0 MODE1 MODE2 Microstep Resolution Low Low Low Full step High Low Low Half step Low High Low 1/4 step High High Low 1/8 step Low Low High 1/16 step High Low High 1/32 step Low High High 1/32 step High High High 1/32 step Specifications 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
