8  STM32 Nucleo-64 board information
8.1 Product marking
The stickers located on the top or bottom side of the PCB provide product information:
• Product order code and product identification for the first sticker
• Board reference with revision, and serial number for the second sticker
On the first sticker, the first line provides the product order code, and the second line the 
product identification.
On the second sticker, the first 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 line shows 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 
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.
8.2 NUCLEO-G070RB product history
8.2.1 Product identification NUG070RB$AU1
This product identification is based on the MB1360-G070RB-C01 board.
It embeds the STM32G070RBT6 microcontroller with silicon revision code "B". The 
limitations of this silicon revision are detailed in the errata sheet STM32G070CB/KB/RB 
device errata (ES0468).
Product limitations
No limitation identified for this product identification.
8.2.2 Product identification NUG070RB$AU2
This product identification is based on the MB1360-G070RB-C02 board.
