Fun fact
"Dupont" is not a standard at all, just a nickname that stuck; the real spec is simply a 2.54 mm (0.1 inch) pin header.
Tips & tricks
Female ends loosen with use. For anything permanent, crimp your own with a proper crimper or solder a header.
Philosophy
The connector of a million weekend projects. Cheap, flimsy, and responsible for more first blinking LEDs than anything else.
