STM32Cube embedded software is a basic set of software components like HAL, LL APIs, middleware and application examples.

STM32Cube Expansion Packages contain embedded software components that complement the functionalities of the STM32Cube and/or enable the usage of a multitude of ST devices in domains such as of sensing, power management, connectivity or audio, together with the most appropriate STM32 MCUs.

These expansion packages build upon, are compatible with the STM32Cube embedded software libraries and tools and enable rapid application development based on proven and validated software elements.

The software packages contain the necessary software extensions as well as implementation examples running on some specific ST development boards. The software architecture allows quick and easy adaptation to user specific hardware configurations.

STM32Cube Expansion Packages can also contain reference codes associated to application notes.

Here are the reference documents to develop and prepare STM32Cube Expansion Packages:
