      I'm using a microcontroller with 3.3V logic. How do I hook up the 8Encoder? It seems specified for 5V.

      Can I just power the encoder with 5V and do the i2c at 3.3V?
      Can I power the encoder with 3.3V? (It seems to work, but not sure if reliable.)
      Or should I use a logic level converter?

      Thanks!

        @mhuis M5Stack uses 5V on the grove cable to cover all bases!
        Most sensors today are 3.3V, but if one is still 5V, it will work.
        Then any M5Stack brand sensors will have a step down power converter to it's internal 3.3v requirement.
        The I2C is 3.3v.
        The 8 Encoder is 3.3v. on the inside (STM microcontroller).
        No logic level converter is needed.

        Cheers, Terry!
