Power Supply

The main power supply is provided through a double connection. These connections are respectively pins 3 and
4 for the +5V and the pins 1 and 2 for the ground (GND). The pins 6, 21, and 24 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.
