4.1.2 Power supply
The main power supply is provided through a double connection. These
connections are respectively the pin 3 and 4 for the +5V and the pins 1 and 2 for
the ground (GND). The pins 6, 21, 24 and 40 are also ground connection in order
to produce a proper ground plane.
A 5V +/-5% - 1A power is strictly required to supply the modem. Otherwise,
serious dysfunctions may appear. However, the modem does not have to
constantly deliver 1A current at 5V on this power supply.
This power supply is internally regulated to a nominal value VBATT.
