Product marking

Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference

design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will

be liable for any customer usage of these engineering sample tools as reference designs or in production.

“E” or “ES” marking examples of location:

•

On the targeted STM32 that is soldered on the board (for illustration of STM32 marking, refer to the STM32

datasheet “Package information” paragraph at the www.st.com website).

•

Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.

Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial

stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number

and is not available for sales.

In order to use the same commercial stack in his application, a developer may need to purchase a part number

specific to this stack/library. The price of those part numbers includes the stack/library royalties.
