Thank you.

Try https://pinout.xyz/

How does that help?

Oh, am I supposed to work it out from that inset diagram below the
main one? If so it's too small to be sure on my laptop screen.

This is ridiculous, I can find nowhere that tells me which end of the

Thank you.

It's in there buried at the bottom of the documentation

This is a handy thing to print out

Great site.

Try this tidbit:

Pin 1 is the only pin with a square solder pad, which may only be
visible from the underside of your Pi.

Yes, that was the first thing I tried. My other Pis have a square pad
but the Pi Zero 2W doesn't, so no help there.

That site includes a graphic showing the orientation

Hmmm. All the pix I see for the Pi Zero 2W are square pin 1, at least on
one side.

Chris,

If nothing else, you *could* have concluded from that reply that googeling
for it yourself could give you what you are after.

Oh, am I supposed to work it out from that inset diagram below
the main one?

What ? From the "Legend" just below it with the text, "A+", "Zero: and "B+"
in *big* letters in the graphic to its right ? Yes, from that one.

Hint : notice the colors of the pins in both the pinout section and the
image in the legend below it.

If so it's too small to be sure on my laptop screen.

That sounds like a "you" problem.

Maybe you should find out how you can "zoom in" with your browser (in my FireFox its ctrl + ). Or use a software or even a hardware magnifying glass (the former is build into Win11).

Heck, you could even take a screenshot, dump it in some image-editing
program (paint?) and use its magnifying capabilities.

But no, instead of saying "thank you" you are whining about how it doesn't work for you, because you have next-to-zero idea about how your browser or google works.

Rudy Wieser

Also note that the rectangular legend around the connecter has one mitred corner; this has been a standard way to denote pin 1 for decades in the electronics indstry.

I've been there etc.

There is a copious amount of online literature on this. The puzzle is
why you couldn't find it yourself...

Really? I haven't uses a 2 W yet, only the W...
But they are supposed to be pin compatible
