An integrated m2m prototyping solution in favor of efficiency
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone implementing interactive projects. Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors and other physical outputs. Arduino projects can be stand-alone, or they can communicate with software running on your computer (e.g. Flash, Processing, MaxMSP). The boards can be assembled by hand or purchased pre-assembled; the open-source IDE can be downloaded for free. Within the range of official Arduino boards, shields, kits and accessories, you can find our GSM Shield for Arduino, the solution which easily integrates the open-source electronics prototyping platform offered by Arduino and our own managed connectivity solutions. GSM Shield is an end-to-end service with a pre-payment model that allows anyone developing m2m solutions to focus on the design and features rather than on the technical details (HW, SW or Connectivity)
This is the GSM Shield.
