Note: "1" represents high level; '0' represents low level; PWM "stands for pulse width modulation wave, which adjusts the duty cycle to change the speed.
IN1, IN2 control DC motor A; IN3, IN4 control DC motor B; The two routes are completely independent.
The input terminal INx has anti common state conduction function, which is equivalent to a low-level input when suspended.
