The GR2 card is a complete GSM/GPRS/GPS solution, based on the Telit GE864-GPS module. The GR2 comes with Python scripting where customer application programs can be stored inside the modem, making the terminal a complete customer solution. The RoHS-compliant GR2 also has a 24 pin connector to provide access to the board power supply, and GE864 serial UART, control lines and GPIO ports. SMA connectors are also provided for the GSM and GPS antennas.
