5 Basic operation

5.1 Hardware design and circuit schematic diagram

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;
Please check the stability of the power supply. Voltage can not fluctuate greatly and 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;
Bottom Layer；

Bottom Layer High-frequency digital routing, high-frequency analog routing, and power routing must be avoided

under the module. If it is necessary to pass through the module, assume that the module is soldered to the Top Layer,
and the copper is spread on the Top Layer of the module contact part(well grounded), it must be close to the digital
