The STM32Cube.AI is an extension pack of the widely used STM32CubeMX configuration and code generation tool enabling AI on STM32 Arm® Cortex®-M-based microcontrollers.
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.
