Bipolar Stepper Motor Driver Board
A3967SLB built-in translator circuit
The Bipolar Stepper Motor Driver Board operates with help of an integrated A3967SLB circuit. This circuit features thermal shutdown with hysteresis, crossover-current protection and under-voltage lockout, and its operation mode depends on the logic state of seven input pins. This translator equips driving step motors with output driver capability of up to 30V and current up to 750mA.
The Bipolar Stepper Motor Driver board is clearly marked, which makes it easier to connect with external electronics. Bipolar stepper motors' stator features two independent coils (A and B). The ending terminals of these coils need to be connected to the CN3 and CN4 connectors (OUT1A, OUT1B, OUT2A and OUT2B pins). Voltage used for driving these coils is supplied on the CN2 connector.
With help of this Bipolar Stepper Motor Driver board, you would be able to drive the motor in different step modes. The size of one increment (resolution) is equal to a movement of rotor generated by one pulse on step input. The resolution is determined by logic state on MSi and MS2 inputs.
