The Bipolar Stepper Motor Driver Board features an A3967SLB complete microstepping motor driver with built-in translator. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with output drive capability of 30V and 750 mA. The board includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay mode. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.
The board has screw terminals for 5-30V power and output to your motors, and a ribbon cable with female 2x10 connector is attached as shown. The pinout matches I/O port headers found on development systems by mikroElektronika, so you can plug this module into one of those systems without having to solder anything.
Use in your own design While this board was created originally for mikroElektronika's development systems, it's certainly possible to use in your own project. To do so, you may want to pick up IDC10 box headers that you can solder onto your PCB, or an EasyTEST board to wire it up easily.
