  • More optimized drivers with a smaller footprint and improved performance
  • Enhanced portability across STM32 devices to reduce development time
  • A more intuitive API for easier and faster application development


To support this update, examples have been revamped for better reusability and understanding, and a new online documentation portal is introduced for enhanced content and easier navigation.
