other parts with large electromagnetic interference.

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
part of the module and routed in the Bottom Layer

Assuming the module is soldered or placed over the Top Layer, it is wrong to randomly route over the Bottom
Layer or other layers, which will affect the module's spurs and receiving sensitivity to varying degrees

It is assumed that there are devices with large electromagnetic interference around the module that will greatly
affect the performance. It is recommended to keep them away from the module according to the strength of the
interference. If necessary, appropriate isolation and shielding can be done

Assume that there are traces with large electromagnetic interference (high-frequency digital, high-frequency
analog, power traces) around the module that will greatly affect the performance of the module. It is
recommended to stay away from the module according to the strength of the interference.If necessary,
appropriate isolation and shielding can be done.

If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (5V communication
level is not recommended, there is still a risk of damage)

The mounting structure of antenna has a great influence on the performance of the module. It is necessary to
ensure that the antenna is exposed, preferably vertically upward.

When the module is mounted inside the case, user could use a good antenna extension cable to extend the
antenna to the outside

The antenna must not be installed inside the metal case, which will decrease the transmission distance greatly.

Chapter 12 FAQ

12.1 Communication range is too short

When there is a straight-line communication obstacle, the communication distance will be attenuated accordingly;

Temperature, humidity, and co-channel interference will increase the communication packet loss rate;

The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing module near
ground.

Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.

The signal will be attenuated seriously when there is metal objects near the antenna or module is put in a metal case.

Power register was set incorrectly, air data rate is set too high (the higher the air data rate, the shorter the
transmission distance).

The power supply voltage is lower than the recommended value under room temperature. (the lower the voltage, the
lower the transmitting power.)

Due to antenna quality or poor matching between antenna and module.

12.2

Module is easy to be damaged

Please check the power supply, ensure it is in right range, voltage higher than max value will damage the module.
