4. Basic operation

4.1 Hardware design

l 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.；
l 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；
l Please check the power supply to ensure it is within the recommended voltage otherwise when it exceeds the
maximum value the module will be permanently damaged；
l Please check the stability of the power supply, the voltage can not be fluctuated frequently；
l When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the
margin, so the whole machine is beneficial for long-term stable operation.；
l The module should be as far away as possible from the power supply, transformers, high-frequency wiring and other
parts with large electromagnetic interference.；
