7 Nucleo-64 boards information
7.1 Product marking
The sticker located on the top or bottom side of the PCB board shows the information about
product identification such as board reference, revision, and serial number.
The first identification line has the following format: ‘MBxxxx-Variant-yzz’, where ‘MBxxxx’ is
the board reference, ‘Variant’ (optional) identifies the mounting variant when several exist,
‘y’ is the PCB revision and ‘zz’ is the assembly revision: for example B01.
The second identification line is the board serial number used for traceability.
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 design or in production.
‘E’ or ‘ES’ marking examples of location:
• On the target 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 that allows the operation of any stack
or library. 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.
The board reference for the STM32 Nucleo-144 boards is MB1136.
