Feature:

Five different step resolutions: full-step, half-step, quarter-step, eighth step and sixteenth step, with output drive capability up to 35 V and ±1.2 A
Adjustable current control allows you to use the potentiometer to set the maximum current output, allowing you to use a voltage higher than the rated voltage of the stepper motor to achieve a higher step rate
No phase sequence table, high frequency control line or complicated programming interface
Over-temperature thermal shutdown, under-voltage lockout and cross-current protection
Ground short circuit and load short circuit protection
Converter is the key to easily realize A4988. Just input a pulse at the STEP input terminal to drive the motor for one microstep.

Warn:

Connecting or disconnecting the stepper motor while the drive is energized will damage the drive.

Package Included:

8 x A4988 stepper motor driver module
