9 Nucleo-144 boards information
9.1 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.
These boards feature a specific STM32H7 device version that 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.
The board reference for the STM32H7 Nucleo-144 boards is MB1364.
9.2 Board revision history
Revision C-01
The revision C-01 of the NUCLEO-H743ZI2 and NUCLEO-H753ZI is the initially released
version.
Revision E-01
The revision E-01 of the NUCLEO-H743ZI2 and NUCLEO-H753ZI removes the limitations
of the revision C-01.
The revision E-01 of the NUCLEO-H723ZG is the initially released version.
