What is the diameter of the pins? The drawing does not seem to say.
Yeah, that is part of the problem. I can't find a datasheet that says exactly. When I bought them, I had no idea there was a difference, it doesn't say anywhere. On the other hand, these are really nice displays and I have breadboarded them successfully so no complaints. I don't have a micrometer that I could measure this sort of thing with. All I can say is probably double the width of a normal pin on an LED display. They are nice, stiff, and strong. I could take a macro picture and post it if that would help. But if anyone has an idea of a header that is useful for this sort of thing, I would be only too willing to buy a couple to try them out and if it doesn't work out I will not "blame" anyone. I am only too willing to experiment.
