Any leads on 40 pin (20x2) stackable pin headers?
I'm still looking for those myself.
The best I've found so far is 10pin stackable headers.
Samtec makes stackable connectors:
Nice find Leon... Thanks for sharing.
Unfortunately stackables are hard to find, and NOT cheap - especially at the 2x20 size.
When I designed Morpheus (2007), I had to order 1000pcs to get even a semi-decent price - and as I recall it had a six or eight week lead time. Later they doubled prices, and stopped making them.
Adam Tech also makes them as I recall.
The PC-104 connector used one 2x32 and one 2x20 stackable header
As Leon points out Samtec makes them, or if you can wait longer Oupiin or 4ucon (taiwan) also have them cheap.
these are nice. 2X20 2.54mm a dollar each
Be sure to get specs from the eBay seller regarding the height of the housing above the PCB. There's some extra plastic on those that could produce a non-standard board spacing.
Let me make sure there isn't a height issue as Phil mentioned and I'll pull them in for stock.
