OpenSTLinux expansion packages can be combined with STM32 MPU OpenSTLinux distribution to enable the use of additional components for a specific feature such as AI-based computer vision, real-time Linux, or GNSS applications. X-LINUX components can be used as software add-ons only or may be combined with hardware shields, such as NFC expansion boards.
The X-LINUX part numbers are offered and maintained by ST, and I-LINUX part numbers are developed and maintained by partners and third parties.
