Years ago I came across springy pins that push into PCB through-hole plated connectors, so that you do not need to solder them - each plated-through hole acts as a socket. But I can't find them now. The idea is that instead of soldering pins onto the Pi Zero, I would have these pins on a board that the Pi could then be pushed on to. The closest I've seen is here: http://www.connectortips.com/use-compli ... r-designs/, but I'm looking for an actual product, with 20x2 0.1 inch spaced pins.
This will save the time of soldering pins on the Pi, and should give a lower profile connection, and might even be cheaper.
Does anyone know if such a thing exists, and where I can order them from?
