A3967 EasyDriver Stepper Motor Driver

The EasyDriver A3967 V4.4 stepper motor driver module is a professional and reliable board for precise control of bipolar stepper motors that is fully compatible with all microcontrollers that produce a digital output of 0 to 5 volts or 0 to 3.3 volts. This module is capable of driving 4, 6, and 8-wire motors, and the maximum output current for each phase is adjustable between 150 milliamps and 750 milliamps, and by means of the internal potentiometer, the current of each phase can be controlled precisely according to the project's needs. The bipolar stepper motor driver board has an internal voltage regulator that sets the digital interface at 3.3 or 5 volts and guarantees safe connection with various microcontrollers. This feature makes the EasyDriver board a suitable option for robotics, 3D printer, and CNC machine projects. Stepper motor control for robotics is one of the main applications of this board and provides the possibility of precise and continuous movement of the motor. The dimensions of this module are 50x20 millimeters and the number of pins is 17, which simplifies installation and use in various projects.

The CNC and 3D printer motor driver module has the ability to adjust the microstep resolution through the MS1 and MS2 pins, as well as control the standby mode or active state of the motor through the sleep and enable pins. The stepper motor driver module, with a voltage of 6 to 30 volts, can power various stepper motors with different voltages, and the higher the supply voltage, the more the torque increases at high speeds.

Current adjustment and microstepping of the stepper motor are performed in the simplest way by the EasyDriver A3967 board, and this provides the possibility for users to adjust the precise current of each phase according to the project's needs.
