A3967 Stepper Motor Driver This A3967 Stepper Motor Driver For Arduino is the most recent version of EasyDriver v44, which was created in collaboration with Brian Schmalz. When compared to previous versions, it offers more flexibility and control over your stepper motor . It is a simple stepper motor driver that is compatible with most microcontrollers and capable of producing a digital 0 to 5V pulse (0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). A 7V to 30V power supply is required for the module's motor. The digital interface is powered by an onboard voltage regulator that can be set to 5V or 3.3V. The A3967 is a full-featured microstepping motor driver with an integrated transistor. It is intended for use with bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with output drive capabilities of 30 V and 750 mA. The A3967 comes with a fixed off-time current regulator that can operate in slow, fast, or mixed current-decay modes. This current-decay control scheme produces less audible motor noise, higher step accuracy, and lower power dissipation. The transistor is essential to the A3967's simple implementation. Simply sending one pulse to the STEP input causes the motor to move one step (full, half, quarter, or eighth depending on two logic inputs). It is not necessary to programme phase-sequence tables, high-frequency control lines, or complex interfaces. The A3967 interface is ideal for applications where a complex P is either unavailable or overburdened. Features: A3967 microstepping driver Adjustable current control from 150mA/phase to 750mA/phase MS1 and MS2 pins are broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth) Compatible with 4, 6, and 8-wire stepper motors of any voltage Breadboard-compatible pins.
