Hi [@tchomaud](https://forum.seeedstudio.com/u/tchomaud)
**SBB0**=Assembly code to let the manufacturer document the assembly number
or product. A way to quickly tell from reading the serial number what the board
is. Up to the developer to determine. So the 4 characters SBB0 may not be always the same as the current version of BBBK.
As we can see from the BBBK datasheet, “36” should represent the year of production.
I think there is maybe an error in the serial number refer to the “20**36**SBB01021”, do you have any other BBBK that could check the EEPROM ID?
Hello Jiachenglu,
Have you got a solution about how I can make the conversion between the label ID et Eeprom ID? As explain in my last post, I got the same issue on other seed board.
Thank you for your answer
