Hailege 2pcs A3967 Stepper Motor Drive Board EasyDriver Stepper Motor Driver for EK1204 Robot

About this item

• •Description:
• •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.
• •Note:When the drive is energized, do not connect or disconnect the motor. This will cause permanent damage to the A3967IC.
• •Package Included:
• •2*A3967 Stepper Motor Driver Board EasyDriver Stepper Motor Driver
