According to https://www.systemplus.fr/reverse-costi … -axis-imu/ website, LSM6DS3, more precisely LSM6DS3TR-C, is the new IMU generation and https://www.st.com/content/st_com/en/se … cts-page=1 defines it as obsolete so, why did you keep the LSM6DS0 breakout and retired LSM6DS3 one?
Variety of reasons; we can’t get the S3 chips (shortage, this version is now about to be ‘obsolete’ as well), and haven’t made a board for the LSM6DS3TR-C (current version)…
But we still have some S0 chips/boards, so those are still able to be produced in the meantime.
Hope this helps make sense of things, and be on the lookout for our S3TR-C version when it’s released!
