So I bought a few larger displays from Futurlec a while ago and now I am going to drive these suckers (MAX7219 to the rescue). But like my other projects, I want to put them into headers rather than making a permanent solder connection. Here are the displays:
The pins are on a 0.2" spacing and fall fine into the normal 0.1" spacing, they just skip every other space. The header I generally use is this one:
It's just too snug for this display's pins. The pins push the header pins out of the header body.
Does anyone know of a similar header that is looser, more play, whatever the term would be? Or any other idea for less-than-permanent mounting for these displays? Thank you!
CrossRoads:
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.
Well standard male IDE header pins are .025" X .025" square with 'filed' points to aid insertion into female IDE sockets pins, but if you don't have a micrometer or other means to accurately measure what you have I don't know what to tell you to do?

I was just sort of hoping someone had trouble similar to this before and could recommend a header that is larger and looser, probably 50% so in each dimension. I am willing to buy a few, eat the shipping, just to try them out.
Ha, I love Harbor Freight and there is one nearby and that is where I got my compressor and extra air tanks, but I have never considered them for precision tools.
I have found some headers that are 0.2" (5.08mm) by design and I think they take the heavier pins. I am going to try to sample a few and if they work I will buy some.
Going to see if they have these calipers at the local shop.
