ELEGOO 120pcs Dupont Jumper Wires
The classic kit: 40 each of male-male, male-female and female-female ribbon cables.
Best for: Every prototyping session
Before anything is soldered, you prototype on a breadboard with jumper wires — and you always need more than you think once a servo driver, encoders and a power module are all in play. Dupont cables in male-to-male, male-to-female and female-to-female let you connect any combination of boards and modules. A solid breadboard-and-wire kit is the cheapest insurance against a stalled build.
