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 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)
– 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
Package includes:
5 x DRV8825 Stepper Motor Driver Module
5 x Heat Sink
