JHXHFJXZ 12V 24V Motor Drive Board H-bridge Motor Speed Controller Module Forward Reverse Rotation Motor Controller for Factories, Schools, Residences

Similar to the L298 control logic, each support three-wire control enable, reverse and brake. The enable signal can be connected to PWM externally, and the forward and reverse control signal can be connected to the limit switch in series. The control signal uses the irrigation current drive mode, which supports the majority of single-chip microcomputer direct drive. All control signals are isolated by optical coupling. There's an electrostatic discharge loop.
