    Hi,

    Could you elaborate the symptoms? Was the measurement wrong, or was it that it refuses to communicate?

    INA233 is very different from INA226 in terms of their digital cores.  Rewriting the software is required for it to work properly. If you haven’t done so, it certainly explains the issue you’re having.
