grounding), must be close to the digital part of the module and routing in the Bottom Layer;
 Assuming that the module is soldered or placed in the Top Layer, it is also wrong to randomly route it in
the Bottom Layer or any other layer, which will affect the spuriousness of the module as well as the reception
sensitivity to varying degrees;
 Assuming that there is a large electromagnetic interference devices around the module will also greatly affect
the performance of the module, according to the intensity of the interference is recommended to stay away
from the module, if the situation permits you can do appropriate isolation and shielding;

Assuming that there is a large electromagnetic interference around the module alignment (high-frequency
digital, high-frequency analog, power supply alignment) will also greatly affect the performance of the module,
according to the intensity of the interference is recommended to stay away from the module, if the situation
permits you can do appropriate isolation and shielding;
 The communication line must be connected in series with a 1k-5.1k resistor if using a 5V level (not recommended,
still risk of damage);

Try to stay away from some TTL protocols where the physical layer is also 2.4GHz, e.g. USB 3.0;
 The antenna mounting structure has a significant impact on module performance. It is important to ensure
that the antenna is exposed and preferably vertically oriented;
 When the module is mounted inside the chassis, the antenna can be extended to the outside of the chassis
using a good quality antenna extension cable;

The antenna must not be mounted inside a metal casing, as this will result in a significant reduction in
transmission distance.
