WINGONEER StepStick 4-Layer DRV8825 Stepper Motor Driver Module for 3D Printer Reprap RP A4988

Features - Simple step and direction control interface - 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 solder-able ground pad below the driver IC on the bottom of the PCB - Six different step resolutio: 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 motor39;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) - Module size, pinout, and interface match those of our A4988 stepper motor drive Package Including 1x DRV8825 Stepper Motor Driver Module
