Description:The module has an interface pinout is almost the same with A4988 stepper motor drive carrier, so that it can be used as a higher performance in a pull-down menu the plates replaced in many applications.DRV8825 features an adjustable current limit, overcurrent and overtemperature protection, six micro-resolution (down 1/32-step).It uses 8.2 - 45V, can provide up to about 1.5 per phase no heat sink or forced air flow (rated up to 2.2 per volume sufficient additional cooling).Feature:Simple step and direction control interfaceThe interface can connect directly with 3.3V and 5V systemsSupport over-temperature thermal shutdown, over-current shutdown and under-voltage lockoutSupport short-to-ground and shorted-load protectionSix different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step4-layer, 2 oz copper PCB for improved heat dissipationAdjustable current control support you to set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step ratesIntelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)45V maximum supply voltageBuilt-in regulator (needed external logic voltage supply)Package included:5 x Stepstick DRV8825 stepper driver5 x Heat sink
