HATDRive! Top: Using 28-pin header extender causes heat up

[Arthur-Philip-Dent]

I received a HATDrive! Top and a HATDrive! Bottom 3 days ago and the work great!

Just assebleing the HATDrive! Top with the included 28-pin header extender didn't work:
Drive was heating up incredibly and not working.

Removed the extender, all works like a charme!
Since I didn't really need the header extender, I don't mind. But maybe its important for other projects to have it.

same issue here, with the GPIO extender the nvme drive is not detected and it heats up. Without the GPIO extender there are no problems.
I was intended to power the Pi via the GPIO pins so, it's not feasible, it seems.
