Super Debug EasyDriver Shield Stepper Motor Driver V44 A3967 Electronic Components Electronic Hobby Kit

EasyDriver Shield stepping Stepper Motor Driver V44 A3967 For Arduino. Instruction: A3967slb is pwm constant current control micro-step drive two-phase stepper motor dedicated drive. Its operating voltage up to 30v, the drive current up to 750ma, a3967slb can drive a two-phase stepper motor, enabling subdivision drive. Chip internal pwm current control circuit can be set by the pfd voltage is set to slow, fast, mixed three current decay mode, if the pfd side of the voltage is higher than 0.6vdd, then choose slow decay mode. If less than 0.21vdd, then select the fast decay mode. Between the two is the hybrid decay mode. In addition, a3967slb also provides comprehensive protection measures, including the suppression of transient voltage, thermal protection, to prevent current through, under voltage self-locking and other functions. a3967slb and the microprocessor does not need to add other interface circuit, the chip mining easystepper Interface, the 8 control lines reduced by 2 (step and direction), simply enter the pulse control stepper motor, the embedded converter can be achieved on the stepper motor control. A3967slb also need some resistance, capacitance to adjust its operating parameters, the entire drive circuit is very simple.
