Does Raspberry Pi Zero have a polyfuse?

Question

The question says it all. If you have a definite answer, it would be great if you could post a photo of the pi zero, where the fuse is pointed out.

The Pi Zero does not have a fuse (polyfuse or otherwise).

See this Raspberry Pi org forum post.

Also see these limited schematics.

It does not have a polyfuse, but good fuses are cheap. If you want a fuse, use a nice glass fuse:

Or a tiny fuse:

To check if you've popped it, just use an ohm measurement. You also do not have to waste a day or more praying that your polyfuse has saved you.

Or add your own polyfuse:
