10. 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 it is within the recommended voltage otherwise when it exceeds the
maximum value the module will be permanently damaged
；
Please check the stability of the power supply, the voltage can not be fluctuated frequently
；
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.
；
The module should be as far away as possible from the power supply, transformers, high-frequency wiring and other
parts with large electromagnetic interference.
