2.3 Parameter description
When designing the power supply circuit for the module, it is often recommended to reserve more than 30% margin,
and the whole machine is conducive to long-term stable operation;
The current required at the moment of launch is relatively large, but often because the launch time is extremely short,
the total energy consumed may be smaller;
When the customer uses an external antenna, the impedance matching degree between the antenna and the module
at different frequency points will affect the size of the emission current to different degrees;
The current consumed when the RF chip is in a purely receiving state is called the receiving current. Some RF chips
with communication protocols or the developers have loaded some self-developed protocols on the whole machine,
which may cause the receiving current of the test to be too large;
