Where to get the 2x15 stacking headers used on the expansion boards



  • Evening, can anyone other some advice on where to get the 2x15 stack through headers for the expansion boards?

    The ones used on the relay expansion:

    If anyone has a part number for compatible header and/or a European supplier that would be great.

  • Surprisingly stacking headers are hard to come by from national stocking distributors. I just checked digikey and mouser and couldn't find anything. I've looked before and I get the impression they are not big stock items.

    For Arduino I've always purchased my stacking headers from specialty suppliers. The thing is they are cheaper there than what I would expect to pay from digikey etc. So probably they are getting their stock directly from China via Aliexpress

    This is the best I could find so far: 2x15 stacking header The store: Hello Electronics has different lot sizes as well if you want more.

    Oh I just realized something. The original Raspberry Pi header is 2x13. Should be lots of those collecting dust. Looking at the expansion dock header pinout it seems that you could center a 2x13 header and still get access to everything you need. Not sure how far that will take you though.

    The raspberry pi header would be 100 mil rather than 2mm however, wouldn't it?



  • @Chris-Stratton Chris, yes the Raspberry Pi header and Onion Expansion headers are 100 mil or ~2.5mm pitch. Perhaps you are thinking of the Omega module headers, which are 2mm pitch?

    I'll have to bite the bullet and get them from China - if there's anyone in the EU who wants some then let me know; I'm going to have some spares :-)
