Faq; Communication Range Is Too Short; Module Is Easy To Damage - Ebyte E107-SC01 Series User Manual

module will also be greatly affected. According to the intensity of the interference, it is suggested to stay away from
the module appropriately. If circumstances permit, appropriate isolation and shielding can be done.
Assume that there are traces with large electromagnetic interference around the module (high-frequency digital,

high-frequency analog, power trace), which 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 (not recommended, there is

still a risk of damage).
Try to stay away from some physical layers and also have a 2.4GHz TTL protocol, for example: USB3.0.

The antenna mounting structure 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, use a good
antenna extension cable to extend the antenna to the outside of the case.
The antenna must not be installed inside the metal case, which will greatly reduce the transmission distance.

8. FAQ

Communication range is too short

8.1
The communication distance will be affected when obstacle exists.

Data lose rate will be affected by temperature, humidity and co-channel interference.

The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing 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 affected when the antenna is near metal object or put in a metal case.

Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the

distance).
When the power supply at room temperature is lower than the recommended low voltage, the lower the voltage is,

the lower the transmitting power is.
Due to antenna quality or poor matching between antenna and module.


Module is easy to damage

8.2
Please check the power supply and ensure it is within the recommended range. Voltage higher than the peak will

lead to a permanent damage to the module.
Please check the stability of power supply and ensure the voltage not to fluctuate too much.

Please make sure anti-static measures are taken when installing and using, high frequency devices have electrostatic

susceptibility.
Please ensure the humidity is within limited range for some parts are sensitive to humidity.

Please avoid using modules under too high or too low temperature.
