It is recommended to use DC voltage regulator power to supply the module, the power ripple coefficient is as small

as possible, and the module should be reliably grounded;
Please note the correct connection of the positive and negative poles of the power supply, if the reverse connection

may cause permanent damage to the module;
Please check the power supply to ensure that between the recommended supply voltage, exceeding the maximum

value will cause permanent damage to the module;
Please check the stability of the power supply, and the voltage cannot fluctuate substantially and frequently;

When designing power supply circuit for modules, it is often recommended to retain more than 30% allowance, and

the whole machine is conducive to long-term stable work;
Modules should be as far as possible away from the power supply, transformer, high frequency wiring and other

electromagnetic interference parts;
High frequency digital routing, high frequency analog wiring, power wiring must avoid below the module, if really

need to pass below the module, assuming that the module is welded in Top Layer, Top Layer in the contact part of
the module with copper (all paved copper and good grounding), must be close to the digital part of the module and
line in Bottom Layer;
Assuming that the module is welded or placed in Top Layer, it is also wrong to walk randomly in Bottom Layer or

other layers, which will affect the stray dispersion and receiving sensitivity of the module to different degrees;
Assuming that there are devices with large electromagnetic interference around the module will also greatly affect

the performance of the module, according to the strength of the interference according to the module, if the situation
allows to do appropriate isolation and shielding;
Assuming that there is a wiring around the module with large electromagnetic interference (high frequency digital,

high frequency simulation, power wiring) will also greatly affect the performance of the module, according to the
strength of the interference is recommended to be appropriate away from the module, if the situation allows to do
appropriate isolation and shielding;
If the communication line uses a 5V level, the 1k-5.1k resistance must be connected in series (not recommended,

there is still a risk of damage);
The antenna installation structure has a great impact on the performance of the module, so make sure that the

antenna is exposed and the best vertical upward;
When the module is installed inside the casing, a high-quality antenna extension line can be used to extend the

antenna to the outside of the casing;
The antenna must not be installed inside the metal shell, which will greatly weaken the transmission distance.
