<![CDATA[8Encoder 3.3V instead of 5V]]>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!

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.
