I'm interested in the NASPi Gemini 2.5, but can't work out if there any UPS hats that are compatible with it. I assume from looking that the X728 isn't compatible as that sits on top of the Pi, and the case looks flush at that point.
There seems to be plenty of space to the "right" of the Pi above the X882 board, so it appears possible to have some form of UPS in that space.
It would be much better to perform the UPS function at low voltage instead of having an inverter and 2 power supplies involved, so I'm keen to hear if there is a combination of boards that will make this possible for a 2-disk NAS in a case.
Many thanks
