Hi. I'm using the Adafruit DS1307 Real Time Clock with a Raspberry Pi Model 4b. It's meant to work at 3.3V, but I can only get it to work at 5V.
Does anyone have any suggestions?
Thanks.

It requires 5v. From https://learn.adafruit.com/adding-a-rea ... ng-the-rtc
DaveConnect VCC on the breakout board to the 5.0V pin of the Pi (if using DS1307)

Thank you.
I need a comment from an Adafruit Engineer on this, due to a product claim.
Kind regards,
Bob

What claim are you referring to? The product description says that it requires 5v power to work.

I assume you are referring to

That just says you can interact with it using 3.3v logic, i.e. a processor that uses 3.3v logic. Like the Pi, for instance. It does not say it can be powered with 3.3v.(although we've used it with 5V power and 3.3V logic successfully)
