Identification IMU

[Nairh]

I have a problem with identifying the sensor type from the marking on the housing. One is LSM6DSO32XTR and the other is ASM330LHHXTR. Unfortunately they came in a bag without a description on the label. One is marked T3 [QR code] 233 and the other LC [QR code] 307.
Is there a way to identify them without attaching them to the board? Unfortunately the datasheet did not help.
Thanks

Welcome @Nairh, to the community!

The LSM6DSO32XTR is marked T3, the ASM330LHHXTR is marked LC.

Hope that helps?

Good luck!

Thank you. It helped, but I must know how to interpret the housing codes. Have I missed something in the Datasheet, or is there no possibility of reverse identification?

The marking code is usually internal information, but is also found on the labels on the packaging, so you should keep a careful record of how it is assigned. The QR code is completely internal information.

The three digits are usually the date code in the form YWW, i.e. the last digit of the year of manufacture and its calendar week.

As I wrote in the first post, there were only parts in the plastic bag, but no markings. Besides IMU there were also barometric sensors LPS28DFWTR, and ILPS22QSTR, but there the resolution was easy due to the different housings. The lack of information about the code meaning on the housings is somewhat unfortunate because it is impossible to check if the delivery is OK.
In any case, thank you for your help.

From whom? ST Microelectronics directly, or some random vendor / distributor?
