INTRODUCTION:
AVR-GSM is excellent board for adding remote monitoring and control in
remote places by GSM cellular network. Do you want to switch on/off
your local heating in your mountain house? To monitor the temperature at
up to 8 remote points up to 30 meters away from the module? To listen
what happens in your house with silent call after you get message for
alarm status? Then AVR-GSM is the board for you! It contains ATmega32
microcontroller and 3-band GSM GPRS module 900/1800/1900Mhz inside
which covers most used GSM networks around the world. The GSM
antenna is build in the board so no need for external expensive GSM
antennas. AVR-GSM have two relays 240VAC/10A, two opto-isolated
inputs which could be connected to alarm sensors or just buttons for user
actions (like call pre-loaded phone numbers), on-board temperature sensor
and connector for additional up to 8 addressable remote temperature
sensors at up to 30 meter distance from the module. Normal phone hook
can be connected to this board and to allow user to speak, listen, taking
and placing phone calls as normal stand alone cellular phone. AVR-GSM
can be connected to PC with the USB connector it have and it is recognized
as modem which could be used to add internet via GPRS to your computer
(imagine how useful is this for your mountain house if there is no internet
but only cellular network!).

POWER SUPPLY CIRCUIT:
The power supply of AVR-GSM could be done in two different ways:
1. Power from +12VDC without using the internal backup battery.
The module is powered only from external 12V and the battery is not
connected. In this case:
− jumper BAT_E must be open
− jumper 4V_E must be closed
− jumper 4V must be closed
− jumper 5V_CHG_E must be open.
Power consumption in this mode is:
− about 60mA when have a conversation.
− About 25mA in normal mode (without conversation) + 60mA if
relays are turned on.
Important: 4V_E, 4V and 5V_CHG_E jumpers have to be
together.
moved
2. Power from +12VDC with backup battery.
The module is powered with battery and allows battery charging. In
this case:
− jumper BAT_E must be closed
− jumper 4V_E must be open
− jumper 4V must be open
Page 9
−
jumper 5V_CHG_E must be closed
− Power consumption in this mode: depend on the battery charge
may vary between 10 and 300mA. If the 12V power supply is
missing the battery discharge current is between 5 and 25 mA
without call, and about 200mA during active call.
RESET CIRCUIT:
AVR-GSM reset circuit is made with STM1001R with typical threshold
+2.63V.
CLOCK CIRCUIT:
Quartz crystal 7.37MHz is connected to ATMega32.

This is standard USB Type B
connector for connection to PC. On board there is FT232RL USB to UART
converter. To use it you should download and install the drivers for your OS
from
http://www.ftdichip.com/Drivers/CDM/CDM20602.zip.
ATMega32 can control FTDI chip as detect USB present and can toggle RST
line of FTDI chip, i.e. the microcontroller decides
whether the
communication is between PC terminal and GSM module or between
ATMega32 and GSM module. When USB cable from PC is connected to
AVR-GSM – ATMega32 allows communication between USB (PC terminal)
and GSM module, when USB cable is removed from AVR-GSM, the
communication is between ATMega32 and GSM module.

Two digital optoisolated inputs are available for user code. The input level
are between 5 and 12V DC.
I2C signals (SCL, SDA) are used for external temperature sensor connection
or other suitable I2C device interfacing.
There is possibility up to 8 external temperature sensors on this bus.
Olimex sell these modules separately under the order code MOD-TMP and
communication with up to 30 meters between the AVR-GSM and MOD-TEM
is possible error free.

power down mode and you press and hold this key for more than 1 second the module will
go in ON mode.
ADC1/PA1: ADC1 input/digital IO of ATMega32.
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.
ADC0/PA0: ADC0 input/digital IO of ATMega32.
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.
(SCK)PB7,(MISO)PB6,(MOSI)PB5,(SS)PB4: ATMega32 SPI pins.
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.
RST: ATMega32 Reset pin. Open collector output.

JUMPER DESCRIPTION:
BAT_E
Connects 3.7V Li-ion battery to the GSM module. Default state
is to be open to not drain the battery during stocking the
modules.
Default state - open
4V_E
When this jumper is open state the DCDC voltage output is set
to 5V, when the jumper is closed the DCDC output voltage is
set to 4V. This is necessary when main battery is not
connected and the supply voltage should be 4V, when the
battery is connected the DCDC voltage should be 5V.
Default state – open.
4V
When the main battery is not present, this jumper feeds the 4V
from the DCDC output to the GSM module.
Default state – open.
5V_CHG_E
The GSM module have build in li-ion charge circuit. This
jumper connects the DCDC 5V output to the internal charger
circuit.
Default state closed
Important: 4V_E, 4V and 5V_CHG_E jumpers have to be
moved together.
Do not plug in external +12V if BAT_E jumper is open!
DCDC_E
This jumper connects the DCDC output to the GSM module. It
is useful to measure the current consumption.
Default state closed
3V_E
This jumper connects +3V to FT232RL and ATMega32.It is
useful to measure the current consumption.
Default state closed
Download
This is GSM module bootloader enable pin. Reserved for GSM
module firmware upgrade.
Default state – open.

MTX/DTX
The GSM module have two UART channels. One for the
commands, one for debugging. With this jumper you control
which chnnel goes to ATMega32 and FT232RL.
MTX/DTX
Default state MTX
MRX/DRX
The GSM module have two UART channels. One for the
commands, one for debugging. With this jumper you control
which chnnel goes to ATMega32 and FT232RL.
MRX/DRX
Default state MRX

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.
