Unit
mA
● When designing current supply circuit, 30% margin is
recommended to be remained so as to ensure long-term
mA
stable operation of the whole module;
● The current at the instant of transmitting may be high,
mA
but the total energy consumed may be lower due to very
short transmitting time;
mA
● When using external antenna, the impedance matching
degree at different frequency points between antenna and
mA
module may affect the transmitting current value at
different levels.
mA
Unit
15 mA
● The current consumed when the RF chip is only working
15 mA
at receiving mode is called as receiving current， the tested
receiving current may be higher for some RF chips with
15 mA
communication protocol or the developers have loaded
their own protocol to the whole module.
22 mA
● The current at pure receiving mode will be mA level, the
users have to realize µA level receiving current through
22 mA
firmware development.
