DRV8825 Stepper Motor Driver Carrier, High Current Features: Suitable for 8.2V~45V (between VMOT and GND for motor), and less than 2.2A (2A for A4988) steppers 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 (1/16 max for A4988) 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
