content: Anyone know where I can find an inexpensive 20 pin (0.1"/2.54mm) header breakout.Likethisbut < $5I'm just looking for a pcb, 3" or so long. 3 sets of 20 pin through holes (for headers) linked by traces.I know I can just fab my own but I figured it was the kind of thing I'd find for a $1 (just the pcb) on AliExpress.

content: Sparkfun and now several other vendors offer bare PCB's with connected PTH holes. You would have to add your own headers and connectors, which will add considerably to the cost.https://www.sparkfun.com/search/results?term=breadboardsAlso check its breakout boards.

That's obviously not going to work as for a 20 pin header (2 rows of 10 pins) you're just shorting one set of 10 pins to the other. There are individual hole protoboards but then I'd have to run all the wires which I don't want to do.

content: Look around the various PCB mans for a shared layout. For example, Oshpark has 1000s of boards you can order that others have designed. I'm sure the China shops have the same "sharing" service.Plan B, find some on ebay

content: Quote from: themadhippy on December 16, 2022, 01:05:03 amI asked this question because I hoped someone knew of the exact pre-made product and could just point me to it.I'm aware I an design my own. I'm aware if I can figure out what they are called that I could find an existing design and have it fabbed.Again, I was hoping someone knew of such an item and could just provide the URL. Thanks!

content: Quote from: dorkshoei on December 16, 2022, 01:53:23 am- If you wanted the specific board in the OP, you should have said "I want this exact board" not "I want like this"- You were already given the answer multiple times yet you refuse to accept it

content: Quote from: thm_w on December 16, 2022, 01:58:37 amNo. I was clear. I was looking for a pre-made board with 3 sets of 20 pin holes. I'm sorry this is so hard for you but don't blame me because of your reading comprehension.QuoteI'll bite. What answer was that? "look for a shared layout".

content: Quote from: dorkshoei on December 16, 2022, 02:04:17 am- Make your own- Find a different way to do itAnother idea would be a board with dual row standard 2.54mm headers that are connected, as long as you don't care that connectors aren't polarized.Worst case I can design the board for you.

content: Quote from: thm_w on December 16, 2022, 02:13:49 amstop please. I said in the OP that I was aware I could make my own. It is ok to seek something specific without having to deflect 1001 suggestions to do it another way. Sometimes there are reasons why you want to do something a certain way. I could I guess have listed all these reasons but then you'd have to read them.lets just move on. i won't be replying to you further.
