extension headers

these should work if the ar not too long

So, you need a few pins' worth of a wire-wrap socket to extend the reach.

Or, you could just replace the 'headers' with taller headers.

Thanks, will check it out. I don't need much length but.

As for reworking the main board's headers, No Thanks. It's quite dense. I could see removing the 5 female headers from the daughter board, and replacing them with longer ones....

Maybe something like this will work

they're called stacking headers.

Right answer. Not easy to find.

since they are used for the arduino shields there are plenty on ebay etc. adafruit also have several sizes

Digikey carries all sorts of things that work. Look under "rectangular connectors" and sort on female headers and then whatever pitch is needed. There are all sorts of different variations but you may need to search different keywords to find them. There are different styles of sockets so you need to find one that matches the existing pins. I found these in a minute or two (I've used all sorts of these things).

Do not know exactly the form/connector format you may be using, but how about Amphenol RVPX-P16DM2, or Molex 90147-1107, or Molex 90151-2120 or similar as "extensions" on one board?

For stacked headers you meed long posts. After selecting gold and instock, only 5 items were left, with 5,6,8,10 and 20 pins. Except for 5 pins, this matches what we can get from Adafruit. The rest are backorder, but OK, claimed to be only 3 weeks.
