3V: Digital power of PIC18F97J60. This is 3VDC output for external digital modules.
GND: Digital ground.
3VA: Analog power supply of PIC18F97J60 microcontroller. This is 3VDC output which can
be used for external analog modules.
GNDA: Analog ground of PIC18F97J60 microcontroller. Can be used for external analog
circuits.
AREF: Analog reference input of PIC18F97J60 microcontroller. Can be used for external
analogue circuits.
VBAT: Dedicated to connect main Li-ion battery. The power supply of GSM module has to
be a single voltage source of VBAT= 3.4V...4.5V. Li-ion battery with 650mA capacity is used
in PIC-GSM.
USB-PWR. +5V output direct connected to +5V of the USB connector.
DCDC-OUTPUT. 5V or 4V output (up to 2A) from DCDC converter depending on jumper
configuration. For details see jumper description section.
+12V(Vin). Input or output terminal for power supply. If the power source is connected to
the module this terminal can use as +12V output . Otherwise this terminal can use for
power source input.
Backup: RTC backup power supply for the GSM module real time clock and RAM, when the
battery is discharged. If the battery attached to this signal is chargeable and the voltage
level is low the module will charge the battery. Vnom = 1.8V, Inom= 20uA
AUXADC: This is general purpose analog to digital converter build-in the GSM module. The
input voltage value should be in range 0V to 2.4V. This pin value can be read with AT
command.
POWERKEY: This is GSM module power on/off key. When the module is ON if you press
and hold for more than 3 seconds the module go in power down state. If the module if in
power down mode and you press and hold this key for more than 1 second the module will
go in ON mode.
GPO1: This is GPO of GSM module and can be configured by AT command for outputting
high or low level voltage. All of the GPOs are initialy in low state without any setting from AT
command.
SPI_DATA,SPI_CLK,SPI_CS,SPI_D/C: This is GSM module SPI port reserved for future use.
KBROW0: This is external keyboard input pin of GSM module.
