This breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 V to 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). The driver has a pinout and interface that are nearly identical to those of our <a href="https://www.pololu.com/product/1182">A4988 stepper motor driver carriers</a>, so it can be used as a higher-performance drop-in replacement for those boards in many applications. This board ships with 0.1″ male header pins included but not soldered in. 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, 2 oz copper PCB for improved heat dissipation • Exposed solderable ground pad below the driver IC on the bottom of the PCB </body></html> This input turns on or off all of the FET outputs. When set to a logic high, the outputs are disabled. When set to a logic low, the internal control enables the outputs as required. The translator inputs STEP, DIR, and MSx, as well as the internal sequencing logic, all remain active, independent of the ENABLE input state.
