A4988 driver Stepper Motor Driver- Good Quality

The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with built-in converter. It includes a fixed off-time current regulator and operates from 8 V to 35 V. The driver automatically selects the current decay mode (slow or mixed) during stepping operation, leading to reduced motor noise, increased step accuracy, and lower power consumption.

• Exceed The Maximum Current Rating Of 2 A Per Coil Without Sufficient Cooling.: This can lead to overheating and potential damage to the driver.

• Use Appropriate Input Voltage Within The Range Of 8 V To 35 Vdc.: This ensures proper operation of the A4988 driver Stepper Motor Driver.
