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.
