Hat for shutting down the Pi with a button

Question

Are there any Raspberry Pi hats which allow to shut down the Pi by pressing a button ?

Are there any DIY open hardware projects which describe step-by-step how to build such a hat ?

No, but there are open software options, such as Adafruit's GPIO-Halt which'll do what you ask, with a default pin of #21, which is the last pin on J8. You change the pin in the .c file, if desired.

I use a Button that flips in 2 ways. One for sending a signal to a GPIO Pin to shut it down via software. And the other to the RUN pin to start it back up again.
