Hello
I baught this nice RTC board
https://learn.adafruit.com/adafruit-ds3 ... ut/pinouts
Is there a SQW output (optional square wave or interrupt output) for interrupt signal.
Is there a way to program it to send a signal each hour, or each x minutes to wake up my Feather MO when sleeping?
Tks
Cheers
[DS3231] can it send a signal each x minutes

No. The available frequencies are all 1Hz or higher. See page 13 of the datasheet: https://cdn-shop.adafruit.com/product-f ... DS3231.pdf
