BOARD LAYOUT:
POWER SUPPLY CIRCUIT:
The power supply of PIC-GSM could be done in two different ways:
1. Power from +12VDC without using the internal backup battery.
2. Power from +12VDC with backup battery.
The module is powered only from external 12V and the battery is not
connected. In this case:
−
−
−
−
−
−
Important: 4V_E, 4V and 5V_CHG_E jumpers have to be
together.
The module is powered with battery and allows battery charging. In
this case:
−
−
jumper BAT_E must be open
jumper 4V_E must be closed
jumper 4V_VBAT must be closed
jumper 5V_CHG_E must be open.
Power consumption in this mode is:
about 240mA when have a conversation.
About 90mA in normal mode (without conversation) and active
WEB interface + 60mA if relays are turned on.
jumper BAT_E must be closed
jumper 4V_E must be open
