2 Ordering information
To order the Nucleo-144 board corresponding to the target STM32, use the order code
given below in
Table 1:
2.1 Product marking
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be
used as reference designs 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 STM32H7 that is soldered on the board (For an illustration of
STM32H7 marking, refer to the STM32H7 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.
These boards feature a specific STM32H7 device version, which allows the operation of any
stack or library. This STM32H7 device shows a ‘U’ marking option at the end of the standard
part number and is not available for sales.
2.2 Codification
The meaning of the NUCLEO-XXYYZT-Q codification is explained in Table 2 with an
example:
The order code is mentioned on a sticker placed on the top side of the board.
