6.6.1. Module Power (Pins 30, 31)
The Enfora Enabler LPP G module uses a single voltage source of VCC=+3.3V to 4.5V.
(The exact values of the uplink currents are shown in the tables in section 5.3.1.)

Please note that the following descriptions are intended to
provide hardware-level definitions. In some cases, specific
lines will have no firmware functionality implemented.
Information for each hardware-specific feature will be noted
in the appropriate section.
The uplink burst will cause strong ripple on the voltage
lines and should be effectively filtered.
External capacitance is not typically required by low current
or extended life applications. However, if capacitance is
added, then current leakage of the capacitor needs to be
taken into consideration for these types of applications.
It should be noted that the input voltage level should not
drop below the minimum voltage rating under any
circumstances, especially during the uplink burst period.
