Electronics

The shield is based on the quad-band SIM 900 GSM/GPRS module. It enables Arduino to work with GSM and GPRS networks. The shield allows making voice calls, sending SMS messages or establishing connections over the internet. The shield has a switch that selects either a hardware or a software serial port connected to the GPRS shield. If you select the software serial port, you will use a software UART otherwise you will use the hardware UART port of the platform. The shield also includes a high-capacity capacitor intended to supply the real time clock module. If you switch the key to the DBG port, you can connect the port to the Arduino and connect it to a computer for debugging.
