Well, I ask that after finding to my surprise that they are not. I bought these low cost M-F jumpers on eBay, and they don’t seem really happy on either end. To ask a really dumb question, do I need the round ones? Or was “DuPont” the wrong thing to buy?
Edit: I guess my google photo doesn’t display. I am going from small motor controller boards (M) to my breadboard (F). The controllers are the standard ones that come with inexpensive 28BYJ-48 steppers. My breadboard is of good quality.
