Stepper Motor Driver A4988 Module

Key Specifications:

  • Voltage (Motor): 8V – 35V (VMOT)
  • Voltage (Logic): 3V – 5.5V (VDD)
  • Continuous Current (Per Phase): ~1A (without heatsink), up to 2A (with adequate cooling/heatsink)
  • Microstepping Modes: Full, 1/2, 1/4, 1/8, 1/16 step
  • Control Interface: Simple STEP (pulse for step) & DIRECTION pins
  • Protections: Thermal shutdown, overcurrent, short-to-ground, shorted-load

Features:

  • Easy to Use: Built-in translator simplifies control (no phase tables needed).
  • Adjustable Current Limit: Set via a potentiometer for motor-specific needs.
  • Low RDS(ON) Outputs: Efficient power delivery.

Typical Applications:
3D Printers, CNC machines, Robotics, and other automation projects requiring precise stepper motor control.
