Re: Arduino Connectors?
¿ªÔÆÌåÓýBob,Besides Samtec you might look for/at the Molex KK series.? Those are .1" excuse me 2.54mm spaced male and female headers.? If you search ebay and Amazon they are often called JST connectors as JST style are used a lot.? The pins are .025" square or round pins and the male headers are usually breakaway style.? I recently bought some of the 20 pin female headers that Rob linked on ebay.? They are not breakaway though.? You do have to cut them and unlike the Molex style you have to sacrifice a pin so if I want a 20 pin female header or 2 of them from the 40 pin strip it ainta gonna happen!? If you try to cut it between pin 20 and 21 you will end up with 2 headers of 19 pins so save yourself some grief and just cut it right over pin 21! In searching I see that Arduino makes or lists those female headers under their brand name.? I just bought a bunch of the 6, 8, and 10 pin stackable female headers from nooelec.com on their ebay store.? I just tried to find them at their non ebay site but do not see them.? Nooelec.com also sells many of the SDR dongles and appears to be their claim to fame. I was just looking and Jameco shows these: I did not look at Adafruit but am sure they also have them. The thing about these "stackable" headers is that they employ long male pins which makes them very convenient for Arduinos because you mount the female header on top of the Arduino and the LONG male pins stick through to also give you the male header to plug in to the module below.? Or you can reverse it depending on whether you need/want the female header on top or bottom but the long pins that go through the board and make the male headers on the other side is very convenient! Here is the Nooelec auction for 200 of the 6 pin female stackable headers: They do seem to be better quality than the ones I have bought from some of the Chinese sellers. When I was looking at Mouser I see that 3M also makes a lot of the male headers and suspect that they have some female headers too but did not look for those specifically. You can also just use a regular 40 pin wide (.6 inch wide) IC socket for I think the Nano in a pinch but IC sockets are not really deep enough.? The stackable ones mentioned above are .4" deep as I recall and an IC socket is maybe 1/16" inch deep or so! I hope that helps. Good luck. Jim Pruitt WA7DUY On 11/8/2019 10:48 AM, Bob Macklin
