This video describes the main components and features of the 
B-L475E-IOT board and shows a typical use of this platform as an IoT node using AWS (Amazon Web Services) to demonstrate the interactions between that node and a cloud server to build an intelligent system.
The focus is put on the MQTT messages exchanges in between the IoT node and a user through AWS IoT services.
These messages contain sensors values and LED status and all the changes detected on the board.
