3.3 Power Supply

The module power supply must be a single external DC voltage source of 3.3V to 4.5V. The power
supply must be able to sustain the voltage level during a GSM transmit burst current serge, which may
reach 2.0A. The module interface connector has 2 pins for the main power supply, as described in the
table. All these contacts must be used for proper operation.
The following table shows the definitions of the pins on the power supply interfaces:
