
It is reco mmended to use a DC stabilized power supply. The power supply ripple factor is as s mall as possible, and
the module needs to be reliably grounded.；
 Please pay attention to the correct connection of the positive and negative poles of the power supply. Reverse
connection may cause permanent damage to the module；
 Please check the power supply to ensure it is within the reco mmended voltage othe rwise when it exceeds the
maximu m value the module will be permanently damaged；
 Please check the stability of the power supply, the voltage cannot be fluctuated frequently ；
 When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the
margin, so the whole machine is beneficial for long-term stable operation.；
 The module should be as far away as possible fro m the power supply, transformers, high -frequency wiring and other

transmit the preamble code of the
corresponding time continuously.
 When the receiver works in mode 2,
the time means the monitor interval
time (wireless wake-up). Only the data
from transmitter that works in mode 1
can be received.
 After turn off FEC, the actual data
transmission rate increases
anti-interference ability decreases. Also
the transmission distance is relatively
short.
 Both communication parties must
keep on the same pages about turn-on
or turn-off FEC.
T he external power must make sure the
ability of current output more than 250mA
and ensure the power supply ripple within
100mV.
Low power transmission is not
recommended due to its low power supply
efficiency.
