Pin Function Description
Interface Schematic
1
NC
Internal circuit node. Do not externally connect.
2
VCC2 GSM Controlled voltage input to the GSM driver stage. This voltage is part of the
power control function for the module. This node must be connected to
VCC OUT. This pin should be externally decoupled.
