Unit
● When designing current supply circuit, 30% margin is
recommended to be remained so as to ensure long-term
70 mA
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
mA
transmitting time.
● 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.
Unit
● The current consumed when the RF chip is only working
mA
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
mA
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
mA
firmware development.
Unit
● The turn-off current means the current consumed by CPU,
µA
RAM, Clock and some registers which remain operating.
SoC is at very low power consumption status.
µA
● The turn-off current is always lower than the current
consumed when the power supply source of the whole
µA
module is at no-load status.
Unit
● If the module stays at maximum voltage for a long time, it
V DC
may be damaged.
● The power supply pin has certain surge-resistance ability,
but the potential pulse higher than the maximum power
V DC
supply voltage.
●The power supply is not advisable to be below 3.0V, or
V DC
the RF parameters will be influenced at different degree.
