PI/
PO
Power supply for the
module
Vmax=4.4V
Vmin=3.55V
Vnorm=4.0V
It must be provided
with sufficient current
up to 3.0A.
It is suggested to use a
TVS to increase
voltage surge
withstand capability.
VDD_RF 1, 2 PO
Connect to external
bypass capacitors to
eliminate voltage
fluctuation of RF
part.
Vmax=4.4V
Vmin=3.55V
Vnorm=4.0V
Do not load externally.
