At the talk yesterday I mentioned the Azure IoT Devkit. This can be used as an IoT Endpoint for Azure among other things and has the benefit of a properly secure architecture including proper security to prevent details being stolen from the device or the device being compromised by naughty firmware. It also has a nice little OLED screen and a whole bunch of useful sensors.
You don’t develop for this device using C# and Visual Studio, but you can use the awesome Visual Micro or Visual Studio code to work in C++.
It’s a great place to start creating proper cloud connected devices.
