What you see on the picture above is A13-SOM-LTE shield which enables 100 Mbit 4G Internet access to A13-SOM.
The LTE shield is specially designed for 4G module from partner we work with. This is the first prototype and some tests should be completed but it’s matter of weeks or months these modules to be released. We still have no price on the 4G module as these are very new but we are assured to have them on the very low cost, so with A13-SOM to enable wearable cloud technology.
100Mbit is enough to listen music, watch videos, log large amounts of data to cloud storage.
A13-SOM-LTE shield is OSHW, the schematic and CAD files are on GitHub.
