StarDiag CAN HSP USB Interface (STN2120)

This interface is based on the powerful STN2120 microcontroller and offers stable, fast, and reliable communication with your vehicle’s control units — ideal for advanced DIY users, workshops, and professional diagnosticians - Multiecuscan, AlfaOBD, Forscan and more. The STN2120 is a high-performance OBD-II to UART interpreter IC. It provides seamless serial communication between a host and a vehicle’s onboard diagnostics system. The STN2120 is fully compatible with the popular ELM327 command set and offers advanced features and extended protocol support.

It is the further development of the well-known Stardiag CAN 327 and other diagnostic protocols such as MS-CAN.
