Description:

The A4988 Stepper Motor Driver is a must-have for building a DIY CNC machine or 3D printer.

• Ideal solution for precise and reliable stepper motor control in CNC plotting, milling, and 3D printer designs
• Controls bipolar stepper motors up to 35V and 2A output current per coil
• Regulated output current provides noiseless operation and eliminates resonance or ringing
• Built-in translator reduces control pins to two, one for steps and one for spinning direction
• Offers five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
• Additional features for reliable operation, including under-voltage, shoot-through, short circuit, overcurrent, and thermal protection
• Technical specifications:
• Motor output voltage: 8V – 35V
• Logic input voltage: 3V – 5.5V
• Continuous current per phase: 1A
• Maximum current per phase: 2A
• Microstep resolution: full, 1/2, 1/4, 1/8 and 1/16
