What is U19 on a Pi 3?

Tue Dec 26, 2017 1:32 pm

Anyone know what is U19 on the back side of a Pi3, by the SD card slot?

This Pi 3 as decided not to boot today. And U19 is getting very hot to the touch.

As it happens I have just attached a Sense Hat to this Pi...

I'm about to remove the Sense Hat and see how it goes.

Still no go with the Sense Hat removed. And U19 getting very hot very fast.

Oddly enough the green activity light flashes as if it is booting as normal. Nothing on the screen though.

Looks like this Pi is dead.

Ah yes. That is what I started to think as it is under the WiFi antenna.

The sense hat is now working on fine on another Pi 3. So it does not look like that killed my Pi.

The dead Pi is still, well, dead.

Which is a shame because it scuppers my plans of getting a Cockroach database cluster running on Pis this Christmas.
