Tutorial: How to use DRV8825/A4988 Stepper Motor Driver Expansion Board 42

This board allows you to increase the power of stepper motor drivers, ideal for 3D printers with heavy loads.

What you need

• 3D Printer
• Stepper motor driver (DRV8825 or A4988)
• Power cable
• Multimeter

Steps

1. 1. Check the specifications of your driver in the datasheet.
2. 2. Turn off the 3D printer.
3. 3. Connect the power cable to board 42.
4. 4. Connect the stepper motor driver to the appropriate pin.
5. 5. Check the maximum current with the multimeter.
6. 6. Verify the correct polarity of the signals.
7. 7. Turn on the 3D printer.
8. 8. Test the functionality with an Arduino sketch.

Example code

```
#include <Stepper.h>

const int stepsPerRevolution = 200; // Cambia se diverso dal tuo motore

Stepper myStepper(stepsPerRevolution, 2, 3, 4, 5);

void setup() {
  myStepper.setSpeed(60);
}

void loop() {
  myStepper.step(stepsPerRevolution);
  delay(1000);
}
```
