AI Fusion HAT+ and PiPower 5 HAT+ compability

Accessories for Raspberry Pi and Arduino
1

I have both the AI Fusion HAT+ and the PiPower 5 HAT+
I would like to use them together, but each one specifically states that the power must be plugged into it.

Is it possible to use these two HAT+ together? If so, which one gets the power connection?

In theory, these two HAT+ units can be used together.

You can:

Connect a battery to the PiPower 5

Then use a USB‑A to USB‑C cable to power the Fusion HAT+

However, you must pay attention to the power‑up sequence:

First, press the power button on the PiPower 5 to supply power to the Fusion HAT+.

Then press the power button on the Fusion HAT+ to power on the Raspberry Pi.

That said, using them together in this way doesn’t really offer much practical benefit.
Since the Fusion HAT+ already has built‑in UPS (Uninterruptible Power Supply) capability, there is generally no need to add a PiPower 5 to power the system.
