A4988 Driver for Stepper Motor

The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with built-in converter, easy to operate. Stepper motors are widely used in various applications that require precise control over motion. To effectively drive a stepper motor, a motor driver is essential. One popular choice among hobbyists and professionals alike is the A4988 driver.

What is an A4988 Driver?

The A4988 driver is a versatile and cost-effective motor driver specifically designed for driving bipolar stepper motors. It provides microstepping capability, allowing for smoother and more precise motor movements. The driver is compatible with a wide range of microcontrollers and can handle a maximum current of 2A per coil.

Key Features of the A4988 Driver:

  • Microstepping capability: The A4988 supports full-step, half-step, quarter-step, eighth-step, and sixteenth-step modes, providing finer control over motor movements.
  • Adjustable current limiting: The driver allows for adjustable current limiting to protect the motor from overheating and damage.
  • Simple control interface: The driver can be controlled using simple step and direction signals, making it easy to integrate into various projects.
  • Thermal shutdown protection: The driver includes built-in thermal shutdown circuitry to prevent overheating.

How to Use the A4988 Driver:

Using the A4988 Stepper driver is relatively straightforward. It requires connecting the driver to the stepper motor and providing the necessary control signals. The driver can be powered using a separate power supply or from the microcontroller itself, depending on the motor’s voltage requirements.

When connecting the driver, it is crucial to follow the correct wiring diagram and ensure proper polarity. Additionally, adjusting the current limit on the driver is essential to prevent motor overheating.

A4988 driver Features:

  • Low RDS (On) Output
  • Automatic current decay mode detection / selection
  • Mix with slow current decay modes
  • Synchronous rectification for low power dissipation
  • Internal UVLO
  • Cross-current protection
  • 3 and 5 V compatible logic supply
  • Thermal shutdown circuitry
  • Ground fault protection
  • Load short-circuit protection
  • Optional step five modes: full, 1/2, 1/4, 1/8 and 1/16
  • Simple step and direction control interface
  • Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-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)
  • Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
  • Short-to-ground and shorted-load protection

Packing List:

  • 1 piece of stepper driver A4988.
