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
ATMega32 can control FTDI chip as detect USB present and can toggle RST
line of FTDI chip, i.e. the microcontroller decides
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.
This is standard SIM card connector, to operate AVR-GSM should have
inserted valid SIM card for your operator network. Note that the SIM card
should be without PIN security.
