Chapter 4 Basic Operation
4.1 Hardware design
 It is recommended to use a DC stabilized power supply to supply power to the module. The power supply ripple
factor should be as small as possible, and the module should be grounded reliably.；
 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 it is between the recommended supply voltages. If the maximum value
is exceeded, the module will be permanently damaged；
 Please check the stability of the power supply, the voltage should not fluctuate greatly and frequently；
 When designing the power supply circuit for the module, it is often recommended to reserve more than 30% margin,
because the whole machine is conducive to long-term stable operation；
 The module should be as far away as possible from the power supply, transformer, high-frequency wiring and other
parts with large electromagnetic interference；
 High-frequency digital wiring, high-frequency analog wiring, and power wiring must avoid the bottom of the
