A4988 Motor Driver Module

This stepper motor driver module can be used separately or in combination with a CNC shield.

Specifications:

• Voltage range: 8-35V
• Maximum current: 1A (continuous), 2A (peak)
• Works with 3.3V and 5V signals
• Current limit that can be set with the potentiometer
• Supports full-step, half-step, 1/4-step, 1/8-step and 1/16-step
• Security built in for high temperatures, high currents, low voltage (UVLO) and short circuit
• Uses synchronic rectification for minimum dissipation
• Comes with cooling block for better cooling
• Pin denominations are listed on the bottom of the module
