Product Use to replace the A4988 to upgrade your 3D printer.
Feature
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 resolutions: 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 motorâ€TMs 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 drivers
Included:
5 x Module
5 x Heat Sink
