Hardware design It is reco mmended to use a DC stabilized power supply. The power supply ripple factor is as s mall as possible, andthe module needs to be reliably grounded.； Please pay attention to the correct connection of the positive and negative poles of the power supply. Reverseconnection may cause permanent damage to the module； Please check the power supply to ensure it is within the reco mmended voltage othe rwise when it exceeds themaximu m value the module will be permanently damaged； Please check the stability of the power supply, the voltage cannot be fluctuated frequently ； When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of themargin, so the whole machine is beneficial for long-term stable operation.； The module should be as far away as possible fro m the power supply, transformers, high -frequency wiring and other
