INPUT/OUTPUT:
Button B1: user button connected to ATmega32 pin.12 PD3 (INT1);
PWRKEY button – 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.
MIC – on-board microphone (voice), with AT command you can switch the
voice audio input to be taken from this microphone of from the handsfree
audio connector.
SPEAKER – voice output for external 32 ohm speaker, with AT command
you can switch the voice audio output to be directed to this speaker or to
the handsfree audio connector.
HANDSFREE – audio 2.5 mm jack voice input and speaker output.
BUZ – audio buzzer , can be used as RING signalization.
Status green LED with name LED connected to ATmega32 pin.16 PD7.
Status red LED with name STAT – indicates the state of GSM module.
STAT is off state – GSM module is not running
64ms On/ 800ms Off – GSM module does not find the network
64ms On/ 3000ms Off – GSM module is connected to the network
64ms On/ 300ms Off - GPRS communication
Optocouple 1 – OPT1 (H11A817SMD) - 5V-12V optoisolated input with
LED2 indication and open collector output connect to ATMega32 pin.40
(PB0(T0)). Positive voltage of '+' terminal and negative voltage or GND of '-'
terminal of OPT_TEMP connector, reflect with log. 0 of Mega32 input.
Optocouple 2 – OPT2 (H11A817SMD) - 5V-12V optoisolated input with
LED3 indication and open collector output connect to ATMega32 pin.11
(PD2(INT0)).Positive voltage of '+' terminal and negative voltage or GND of '-'
terminal of OPT_TEMP connector, reflect with log. 0 of Mega32 input.
Relay1 – REL1 240VAC/10A (RAS1215) with default tied Normal Close (NC)
and COM terminals and disconnected Normal Open and COM terminals.
LED_R1 (Red) indicated when turn on REL1. The relay is turned on with
log 1 of PC7 port.
Relay1 – REL2 240VAC/10A (RAS1215) with default tied Normal Close (NC)
and COM terminals and disconnected Normal Open and COM terminals.
LED_R2 (Red) indicated when turn on REL2. The relay is turned on with
log 1 of PC6 port.
