Hi,
I am considering doing a small build with inky phat and a pi zero. I would like 3 small physical buttons as well. Is this possible given pin requirements?
The pinout is here
You can use any of the GPIO not in use by the Inky. You may want to put something like a Proto Zero between the Pi and inky to get access. Use a stacking header on the Proto Zero
You could also use a Button SHIM instead of wiring the buttons yourself, if the button position isn’t an issue. I doubt any home-made job would be as compact as that.

Forgot about the Button Shim, that’s a really good idea. I wish they wouldn’t call it a shim though, it does require soldering on a header, or soldering it to the Pi’s header.
