A4988 Stepstick Stepper Motor Driver

A4988 Stepstick Stepper Motor Driver with Translator and Overcurrent Protection (35V, 2A)

Upgrade your 3D printer or DIY electronics project with the A4988 StepStick Stepper Driver. This breakout board is designed for Allegro's A4988 DMOS microstepping driver and provides reliable performance for bipolar stepper motors in various stepping modes.

Features

• Simple Interface: The A4988’s translator allows easy operation, requiring just one pulse on the STEP input to move the motor one microstep.
• Multiple Step Modes: Operates in full-, half-, quarter-, eighth-, and sixteenth-step modes for precise control.
• Adjustable Current Control: Set the maximum current output with a potentiometer, allowing for voltages above the motor’s rated voltage for higher step rates.
• Intelligent Chopping Control: Automatically selects between fast and slow decay modes for optimal performance.
• Comprehensive Protection: Includes over-temperature thermal shutdown, under-voltage lockout, crossover-current protection, short-to-ground, and shorted-load protection for safe operation.

Important Warning

Do not connect or disconnect the stepper motor while the driver is powered, as this can damage the driver. Always ensure the device is powered off before making wiring adjustments.

This A4988 StepStick Stepper Driver is perfect for applications where complex microprocessor control is unnecessary or unavailable. Enhance your project’s performance with this reliable, easy-to-use driver!
