●When designing current supply circuit, 30% margin is recommended
to be remained so as to ensure long-term stable operation of the
whole module;
●The current at the instant of transmitting may be high, but the total
energy consumed may be lower due to very short transmitting time;
●When using external antenna, the impedance matching degree at
different frequency points between antenna and module may affect
the transmitting current value at different levels.

●The current consumed when the RF chip is only working at receiving
mode is called as receiving current，the tested receiving current may
be higher for some RF chips with communication protocol or the
developers have loaded their own protocol to the whole module;
● The current at pure receiving mode will be mA level, users can
realize µA level of receiving current through firmware development.

● The turn-off current means the current consumed by CPU, RAM,
Clock and some registers which remain operating. SoC is at very low
power consumption status;
● The turn-off current is always lower than the current consumed
when the power supply source of the whole module is at no-load
status.
