Product Model: OKY3905 3D Printer Stepper Motor Driver Module DRV8825 Stepper Motor Driver Controller Product Description
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.
Can interface directly with 3.3V and 5V 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.
Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects.
