The Bipolar Stepper Motor Driver Board comes designed to let the user operate bipolar stepper motors in full-, half-, quarter-and eight-step modes. This additional board comes equipped with a complete microstepping motor driver with an in-built A3967SLB translator. The accessory board also includes a fixed off-time current regulator, which is capable of operating in slow, fast, or mixed current-decay mode. This current-decay control scheme not only increases step accuracy but also results in less power consumption and much reduced audible motor noise.
The Bipolar Stepper Motor Driver Board, which is available as a stand-alone device, can also be connected to the microcontroller. For establishing the connection of the Bipolar Stepper Motor Driver to the microcontroller on the development system, the user needs to use a flat cable with a regular IDC female connector. This female connector in turn should be connected to some development system.
