INTRODUCTION
With the blooming development of IoT (Internet of Things), more and more people are dedicated to pursue their own IoT dreams. However traditional IoT technologies are mainly evolved on the basis of Wi-Fi features, which leads to a barrier of development related to Geo-limitations that IoT projects cannot be implemented in to outdoors. In light of the popularity of bike-shared system in recent months, GSM Data Communication has been reconsidered as the best choice for outdoor IoT solution.
The Gravity: A6 GSM & GPRS Module is a new GSM & GPRS communication module presented by DFRobot. Differ from traditional IoT development modules, Gravity: A6 enables its functions basing on GSM instead of Wi-Fi. It can make a call and send text message with the small and portable GSM SIM card. This technological advantage expand the space of IoT application, for the outdoors in particular.
By means of Gravity:A6 features, you can DIY a telephone with a 3.5mm headphone port. Gravity:A6 also works well in different situations with onboard 1500uF electrolytic capacitor and without any external power supplies even in the instantaneous high current . The module Uart port level is only 2.8V, which means it is compatible with Arduino, Raspberry-Pi and other controllers.
NOTE:
Please plug in a standard SIM card in this module. Users of Micro-SIM and Nano-SIM should use a card set.Only support GSM Network.FEATURES
