SIM900 GSM/GPRS Module

INTRODUCTION

This is a SIM900 GSM/GPRS module working under 3.3V. Unlike other GSM/GPRS modules, this modules works with most 3.3V system such as intel edison, and Arduino Due.

It has a quad-band GSM/GPRS engine. The standard industrial-level interface makes it easy to configure via AT commands.

Through this module you can do almost everything that feature phone does. Imagine that every morning, your "private robot secretary" calls your phone and say "good morning". It will be really cool!

NOTE: SDK or drivers for Gadgeteer platform not included. Drivers are a community maintained projects, for contributions please forward directly to Github or Codeplex.
