IMU Identification Code

I have a problem with identifying the sensor type from the marking on the housing. My understanding is the first two digits of the code are how you identify the part, but I could not find a good key to decipher it.

The two digit code is “3B”

Would it be possible to identify the part number based off this code?

Welcome ​@AaronS, to the community!

With the extremely large number of devices that STMicroelectronics has in its portfolio, a two-digit marking cannot be unambiguous. But you could check the ISM330BX.

Hope that helps?
