Installation and Usage

Follow these guidelines to get reliable performance from your DRV8825 module.

Basic Wiring

• Supply VMOT and GND with a suitable motor power source within the recommended voltage range.
• Connect STEP and DIR pins to the pulse and direction outputs of your controller or microcontroller.
• Use ENABLE to enable or disable the driver as needed.
• Connect motor coils to the A+/A- and B+/B- outputs following your motor datasheet.

Microstepping Configuration

Microstepping is configured using the module’s microstep pins (MS/M0-M2). You can select full, half, quarter, eighth, sixteenth, and finer steps up to 1/32 for smoother motion and reduced resonance. Consult the module documentation for the exact pin combinations available on your board.

Current Adjustment and Tuning

• Adjust the motor current using the onboard potentiometer. Make adjustments gradually and monitor motor and driver temperature during setup.
• Always set the current limit according to your stepper motor rated current to avoid overheating or missed steps.
• Power off the board before making wiring or major adjustments.

Cooling and Mounting Tips

• Ensure adequate airflow around the aluminum heat sink for best thermal performance.
• For sustained high-current use, consider additional cooling such as a fan or larger heatsink.
• Mount the module on standoffs to improve airflow and prevent short circuits.

Protection and Reliability

The DRV8825 module includes built-in protection mechanisms to enhance durability and safety:

• Thermal shutdown to prevent damage from excessive temperature
• Overcurrent protection to guard against short circuits or stalled motors
• Undervoltage lockout to ensure stable operation when supply voltage falls below safe levels
