Cable and Header Parts:

I mostly use 0.100″ spaced connectors, which will match the default spacing of breadboards and the connectors on virtually every kind of microcontroller.  Far as I can tell, the cheapest way to get breadboard pin headers is on amazon:

Here’s a handy series of shrouded, latching headers I’ve used in multiple projects. Molex is the cheapest source for all of these – be careful about picking TE Connectivity, which sources nearly identical parts for a higher cost. 4Pin is just an example, the series goes from 2 slot all the way up to 8+.

Sourcing the parts for single-slot terminals (like the ones you find on Adafruit jumper wire) is actually way harder. Molex and TE both lack cheap options for this on Digikey so you have to go elsewhere. Here’s some good ones on Pololu, along with a two-pin unlatched option for those two-row pin headers on many microcontrollers. They can be male or female depending on the terminals you load.
