I was looking for suggestions for a low profile, polarized 2-pin power connector header, suitable for PCB mounting at 0.1" pitch spacing.
Note, the pins don't have to be spaced at 0.1", just a multiple of that, so it can be mounted (e.g.) on standard protoboard.
Low profile in the sense the header sits less than 8mm above the PCB.
I was looking at the JST XH headers,
which have a 2.5mm pitch, so would be OK as far as the PCB/protoboard mounting goes, and they are low profile, but they look a bit tiny and fiddly to work with. Overall, I think I'd prefer something a little beefier. Also, they also look like crimping the tiny pins for the connectors could be a pain. I'd prefer to be able to solder pins rather than crimp if that was an option (but not a deal breaker.)
