I'm looking to buy a couple of those male connector things that servo pigtails can slide over or into. They have 3 output leads that just stick down into a breadboard, and the pigtail connection can just connect right into them. Hope someone knows what I'm talking about.
The connectors can be specific so you can plug them in the wrong way, but a 0.025" square header with a 0.100" spacing is a real common part until the electronics industry went metric.
