STM32WL Nucleo-64 board information
8.1
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 designs or in production.
“E” or “ES” marking examples of location:
•
On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the
STM32 datasheet “Package information” paragraph at the
•
Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.
