Max Unit
● 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
mA
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.
Max Unit
● 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
25.3 mA
loaded their own protocol to the whole module.
● The current at pure receiving mode will be mA level, the
users have to realize µA level receiving current through
firmware development.
Max Unit
The turn-off current means the current consumed when
●
CPU, RAM, Clock and some registers remain operating while
SoC is at very low power consumption status.
4.5 µA
● 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.
