● The communication level is higher than the maximum
value of the module communication level, there is a high
risk of burning the module;
V DC
● Although there are many ways to change the
communication level, it will greatly affect the power
consumption of the whole machine.
Unit
Remark
● Since the material itself has a certain error, a single LRC
component has an error of ±0.1%. However, since a
plurality of LRC components are used in the entire RF loop,
there is a case where error accumulation occurs, resulting in
a difference in transmission current of different modules;
dBm
● Reducing the transmit power can reduce power
consumption to some extent, but reducing the transmit
power emissions for a number of reasons reduces the
efficiency of the internal PA;
● Transmit power will decrease as the supply voltage
decreases.
Unit
Remark
● The current sensitivity is tested at an air rate of 2.5kbps.
● Since the material itself has a certain error, a single LRC
component has an error of ±0.1%. However, since a
plurality of LRC components are used in the entire RF
loop, there is a case where error accumulation occurs,

resulting in a difference in receiving sensitivity of different
modules;
● After increasing the airspeed of the module, the receiving
sensitivity will decrease, resulting in a decrease in
communication distance.
