I remember there was a link on wiki to ebay lot, where I can buy 4-pin JST-SH connectors, but now I can't find both - link and ebay lot.
Anyone knows where I can get them?
Digikey is not an option - delivery costs 10 times more than connectors itself.

I ordered these about 2 weeks ago but haven't received them yet

Let me know how they fit. The only reason I did'n order them is female connector looks a little bit different form what we see on CC. Pins are too short and mounting pins are at the side of pins, not at the side of male connector.

damn, I sure hope they fit

I got those too, and they fit fine.  But they are so tiny, it is really tricky to solder the female socket.  I'll have some pictures later on my XBee thread.

Those are 1.0mm pitch, so are the correct ones.   I got tired of trying to see through the various magnifiers and went all out for a Christmas stereo microscope!  Night and day difference, I can now see a .5mm pad like looking at my hand in front of my face.

I've got myopia, something around -4 dioptries. That is too bad that I have to wear glasses, but I can solder and inspect .5mm pitch with no problem

Good news
Do they have connectors on both sides of the wire or not?

Wiki also points to that item:

and I believe I've bought them from the same seller few months ago, they fit.

The male JST-SH plug is connected to 4 long wires and is easy to deal with.  The female socket just has four long, thin metal contacts along the plastic (not sticking out).  Not sure how you are supposed to connect to it, but I did manage to solder four tiny wires to the contacts using a lot of masking tape.  That connection has no strength, however, so I gobbed it up with hot glue.  Would be great to learn if there is a proper way to do this.  It would be much easier to cut an extension cable, but I didn't get one.

They are meant to be surface mounted to a PCB, not for directly soldering a cable to them. As you said, a direct solder connection is not very strong. A small breakout board would probably be the better choice.

That is the difference I was talking about. CC connectors have a small leads.

My PCBs got stuck for a Chineese New Year, so I got 2-3 more weeks to find exact connectors...
Thanks alot, will keep ebay as backup option
