Max Unit
● When designing current supply circuit, 30% margin is
30.8 mA
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,
30.8 mA
but the total energy consumed may be lower due to very
short transmitting time;
154 mA
● When using external antenna, the impedance matching
degree at different frequency points between antenna
and module may affect the transmitting current value at
154 mA
different levels.
Max Unit
● The current consumed when the RF chip is only working
29.7 mA
at receiving mode is called as receiving current，the tested
receiving current may be higher for some RF chips with
29.7 mA
communication protocol or the developers have loaded
their own protocol to the whole module.
46.2 mA
● The current at pure receiving mode will be mA level, the
users have to realize µA level receiving current through
46.2 mA
firmware development.
Max Unit
● The turn-off current means the current consumed when
1.8 µA
CPU, RAM, Clock and some registers remain operating while
1.8 µA
SoC is at very low power consumption status.
● The turn-off current is always lower than the current
1.8 µA
consumed when the power supply source of the whole
1.8 µA
module is at no-load status.
Max Unit
● If the voltage is at maximum value for long time, the
3.6 V DC
module may be damaged
● The power supply pin has certain surge-resistance ability,
3.6 V DC
but the potential pulse higher than the maximum power
supply voltage;
3.6 V DC
● The power supply voltage is recommended to be higher
than 3.0V, if the voltage is lower than 3.0V, the RF
3.6 V DC
parameters will be affected at different degrees.
