Basic Electronics » Miniature headers

I have a AT90USBKEY2 Atmel development board.

The PCB has miniature header pinouts, well I am not sure what you actually call them.

The top three and bottom three headers to the left are smaller that the standard header on the top right.

I have no idea of the spacing for the pins or the what solder header would be called!

Anyone know what I need to put some headers on and than what wire connector headers?

According to ATMEL DOC7627.PDF AT90USBKey Hardware User Guide Page 19, they are 1.27mm (.05") spaced header connectors, but looking at the board photo, it seems while they may have a .05" space length wise, they have .1" width wise. If you line up a double row header you have, does it hit every other hole length wise and fit width wise?

Hi Rick, Happy New Year!!!

re: "does it hit every other hole length wise and fit width wise?"

Yes exactly

I had seen that 1.27 reference on the schematic but was not sure what it was referencing.

Now I see it listed in the Bill of Material.

Once again you are a life saver.

Thanks,

Ralph

What would you use for wiring a 1.27 header?

I'd have to research more, a quick look at Mouser and I didn't see any connectors with that layout. Most were .05 x .05 (1.27 x 1.27).

If I couldn't find the right connectors, I'd probably solder wires.

Molex has the 1.27 Custom board Headers.

But no reference to wiring headers.

Strange.
