YINGHUA A4988 Stepper Motor Driver Module 5-pack 3D printers accessory

SKU CH-YJ1P-W3D9T

Pack of five A4988 stepper driver modules with heatsinks, offering up to 35 V and 2 A output plus five micro-step resolutions

  • Five micro-step resolutions for smooth motion control
  • 35 V and 2 A output capacity drives larger motors
  • Thermal shutdown and under-voltage lockout protect hardware
  • Compact 20.56 x 15.26 x 11.59 mm PCB fits tight builds
  • Five modules in one pack for multi-axis printers

YINGHUA A4988 driver module 5-pack

This pack contains five A4988 stepper motor driver modules intended for 3D printer controller boards. Each module provides simple step and direction control with five selectable microstepping resolutions from full-step to sixteenth-step. The modules are suited for hobbyists and makers building or repairing Cartesian or delta printers.

Check voltage logic and pinout before ordering

Verify that your controller board runs compatible logic levels and that the pin header spacing matches the module footprint of approximately 20.56 x 15.26 mm. Confirm the motor supply voltage does not exceed 35 V and that the required phase current stays within the 2 A rating. Take anti-static precautions during handling to avoid short-circuit damage.

Thermal shutdown and heatsink included

Each module includes a heatsink and features over-temperature thermal shutdown, under-voltage lockout and crossover-current protection. In normal operation the driver will throttle or shut down if the junction temperature rises excessively, keeping noise limited to the stepper motors themselves. Power draw scales with motor load up to the 2 A per phase limit.

Questions about this item

What comes in the pack and what else is needed to run the A4988 modules?

The pack contains five A4988 stepper motor driver modules with heatsinks. You must supply a compatible controller board, stepper motors, a power source up to 35 V, and wiring.

Which of the five step resolutions should I select for my printer?

Choose full-step for maximum speed, half-step or quarter-step for a balance, and eighth-step or sixteenth-step when you need the finest positioning accuracy.

What does the 2 A output rating mean when the module is installed in a 3D printer?

Each driver can deliver up to 2 A per phase to a stepper motor, so size your motor current and cooling to stay within that limit during printing.
