A4988 is a chip designed to control stepper motors with microsteps. There are full, half ¼, 1/8 and 1/16 bipolar motor drive modes. The motor drive voltage supports up to 35v volts. It can drive up to 2A motor and its current can be controlled by the current regulator. It sends a signal to one phase of the stepper motor in each signal. The rotation step of the motor can be counted according to the motor type used.

Features:

• automatic current control
• Current drop control
• Synchronous rectification (for low power consumption)
• Built-in UVLO
• Reverse current protection
• Logical 3.3v or 5v option
• temperature protection
• Short circuit load protection
• 5 different pitch options: full, 1/2, 1/4, 1/8, 1/16

Scope of application:

• 3d printer
• CNC machines
• Sumo robots
• camera position controller

Package Included:

• 1x A4988 Stepper Motor Driver Board
• 1x Aluminum heatsink
