Handy Tips for Using the 120Pcs DuPont Jumper Cable Bundle – 20cm:
1: This bundle includes all three connector combinations in one pack — Male to Male (breadboard to breadboard), Male to Female (breadboard to module pin header), and Female to Female (module to module). Having all three types on hand covers virtually every common prototyping wiring scenario.
2: The 20cm length is the most versatile all-round size — long enough to comfortably reach across a full-size breadboard or connect to an external module, but short enough to keep your workspace neat and manageable. It is the go-to choice when you are unsure which length to stock.
3: The multicolour wires are not just cosmetic — use a consistent colour convention throughout your project to make debugging easier. A common convention is: Red = VCC/Power, Black or Brown = GND, Yellow = Signal, Blue = SDA, Green = SCL, Orange = TX, White = RX.
4: DuPont connectors are designed for repeated insertion and removal, but excessive force or sideways stress will loosen the pin contacts over time. Always insert and remove connectors by gripping the plastic housing — never pull by the wire itself.
5: These cables are fully compatible with standard 2.54mm pin headers, Arduino boards, Raspberry Pi GPIO, ESP8266/ESP32 modules, breadboards, and most development boards and sensor modules available on the market.
