Has anyone seen Breadboard Compatible Spring-Terminals, Screw-Terminals, or other methods? We’re a bit exhausted of working with these tiny wires, constantly trying to thread them in and out, but all of the terminals we’ve seen so far are spaced too widely, or the posts are too big, for Breadboards.
I’ve started getting into making custom breadboard cables. Pololu.com sells crimp connectors for various # of pins, from 1x1 to 2x16 that you can make whatever custom cable you want:
So for about $22, you can get the crimp pins, and 1x1, 1x2, 1x3, 1x4 connectors to try it out.
Figure $52-55 if you don’t want to crimp your own cables, and want 6" cables in various MM, MF, FF orientations. Add another $30 for the cheaper crimping tool.
Rather than getting MM, MF, and FF versions of the 6" wires, I’ve been using only FF wires, and then these extra long male headers that fit in the breadboard, and allow female cables to be mounted: http://www.adafruit.com/products/400.
A somewhat different approach is to use locking wafer connectors. This site sells a bunch of male/female connectors and crimp pins that fit on stranded wire (it fits better than on solid wire). You get a selection of 3, 4, 5, 6, 8, and 10 connections. You will need to leave extra space on your breadboard for these connectors: Straight Wafer Header Male/Female 3,4,5,6,8,10-pin PCB to Wire 6 Types 10/ea - dipmicro electronics
Another place has these JST connectors (I don’t know if the JST connectors are the same as the wafer connectors above). You can get a basic JST set for making cables with 2, 3, and 4 connections http://www.robotshop.com/en/254mm-jst-connector-kit.html.
If you wanted terminal blocks that you could just put in wires without crimping, you can get these. Both Sparkfun and Adafruit sell a few versions of these, but pololu.com has more variety of # of pins, and is cheaper. You want the 0.1" pitch for a breadboard. Depending on the breadboard layout, you might want the versions where the wire attaches to the top of the side: http://www.pololu.com/category/117/terminal-blocks.
You could also go for a prototype shield with screw connectors. I got this, but I don’t like the layout of the connected holes in the prototype part of the shield, and never used it: http://www.robotshop.com/en/dfrobot-proto-screw-shield-assembled.html.
