10Pcs Geekcreit 3D Printer Stepstick DRV8825 Stepper Driver Reprap 4 Layer PCB
Descriptions: 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). Features: - Simple step and direction control interface - The interface can connect directly with 3.3V and 5V systems - Support over-temperature thermal shutdown, over-current shutdown and under-voltage lockout - Support short-to-ground and shorted-load protection - Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step - 4-layer, 2 oz copper PCB for improved heat dissipation - Adjustable 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 rates - Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) - 45V maximum supply voltage - Built-in regulator (needed external logic voltage supply) Package included: 10 x Stepstick DRV8825 stepper driver 10 x Heat sink
