FAQ：
Q: What is the limit of the dead time range?
A: The dead time should be less than half of the negative pulse width of PWM1,
that is, DeadT<(1/Freq*(1-Duty))/2; for example, the frequency is 2K and the duty cycle is 90%, then
the dead time should be less than 25us;

Q: What if the dead time is set too large?
A: If the dead time is set too large, one of the complementary signals will not be output.

Q: What is the situation when the product is connected to the circuit without display?
A: Check whether the power supply voltage is normal and whether it is between 4-28V

Q: Can it be powered by batteries?
A: Yes. The module has a wide power supply voltage. As long as the battery voltage is within the product's nominal power supply range, it can be powered by batteries.
