- ref is the reference voltage;
- gnd to logic ground and power ground;
Specifications
- rc1, rc2 h bridge fixed deadline for the analog input.
- a3967slb between the microprocessor and other interfaces without additional circuitry, the chip mining easystepper
- Interface, eight control lines decreased 2 (step and direction), simply enter the stepper motor control pulse, its embedded converter can be achieved on the stepper motor control.
- a3967slb also need some resistor and capacitor to adjust its operating parameters, the driving circuit is very simple
