https://www.sparkfun.com/products/14846 7.5" ePaper display
https://www.sparkfun.com/products/14846 PaPiRus hat

I have the hat and I have it working on my pi with the included 2.7" display, but we'd like to get it working with a larger display for informative purposes.
I'd like to know if the 7.5" display I linked will work with the hat or not. The ribbons look similar in photos, but that can always be deceptive.

Sorry for the late reply!

The PaPiRus Hat appears to have a different interface for it's ePaper panel than the interface for the 7.5" display. For that reason, they are most likely not compatible.
