Original Chip with Retail Package Red A4988 Stepper Motor Driver (with Heatsink,1.5A)
The A4988 Stepper Motor Driver is a comprehensive micro-stepping motor driver featuring a built-in converter, ensuring straightforward operation. Operating within a voltage range of 8 V to 35 V, it can deliver approximately 1 A per phase without the need for a heat sink or forced air flow. With sufficient additional cooling, it’s rated for 2 A per coil.
This driver incorporates a fixed off-time current regulator, offering the flexibility of slow or mixed decay modes. The converter plays a pivotal role in facilitating the seamless integration of the A4988.
Unlike some drivers, there’s no requirement for phase sequence tables or complex high-frequency control interface programming. This makes the A4988 ideal for scenarios where a sophisticated microprocessor isn’t available or is overloaded. During stepping operations, the chopping control within the A4988 automatically selects the current decay mode, enhancing step accuracy while minimizing audible motor noise and reducing power consumption.
Furthermore, internal synchronous rectification control circuitry is provided to optimize pulse width modulation (PWM) power consumption during operation.
The A4988 is equipped with internal circuit protection mechanisms, including thermal shutdown with hysteresis, under-voltage lockout (UVLO), and crossover current protection. It doesn’t necessitate special power-up sequencing.
Packaged in a surface mount QFN package (ES) measuring 5 mm × 5 mm, with a nominal overall package height of 0.90 mm, it also features an exposed thermal pad to enhance heat dissipation capabilities.
Features:
- Automatic current decay mode detection/choice.
- Mixed with slow current decay mode.
- The low power dissipation of synchronous rectifier.
- Internal UVLO (ultra voltage lockout).

Frequently Asked Questions
What is the recommended maximum current for this A4988 driver?
This A4988 board delivers around 1.0 A per phase without additional cooling. With the included heatsink and adequate airflow, you can safely push up to 2.0 A per coil. The retail package is rated for continuous 1.5 A use.
How do I select the micro-stepping resolution?
The module features three MS pins (MS1, MS2, MS3). Tie them high or low according to the truth table:
• Full step: all low
• Half step: MS1 high
• Quarter step: MS2 high
• Eighth step: MS1+MS2 high
• Sixteenth step: all high
Can I drive this board with a 12 V power supply?
Yes. The A4988 supports any DC input between 8 V and 35 V, so a 12 V supply is ideal for typical NEMA stepper motors while keeping heat generation manageable.
