The Narobo DroneCell makes it easy to build wireless projects based on cellular telephone technology. When equipped with an active SIM card (not included), the DroneCell becomes a GSM/GPRS quad-band cell phone with a TTL serial interface, enabling remote control of your project anywhere there is cell phone reception (e.g. control your robot in Los Angeles from your laptop in New York City). It can communicate via text messages (short message service), via phone calls, and over the Internet. The header pins have 0.1" spacing, making this cellular module compatible with standard solderless breadboards and 0.1" perfboards.
