4.1 Hardware design

It is recommended to use a DC stabilized power supply. The power supply ripple factor is as small as possible and
the module needs to be reliably grounded;

Please pay attention to the correct connection of the positive and negative poles of the power supply,
reverse connection may cause permanent damage to the module;

Please check the power supply to ensure that between the recommended supply voltage, if exceeding the maximum,
the module will be permanently damaged;
