Custom Wire Connectors





Introduction: Custom Wire Connectors

Make your Arduino prototype projects more professional looking, organized, and more solid.

Step 1: Bits and Pieces

  • The DuPont rainbow wire commonly comes in 40pin strips and I recommend sticking to the female ends when customizing. (With or without housing.)
  • Various preferred sizes of housing connectors.
  • Optional: Long Male Header Pins ;-)

Step 2: Remove the Housing

Remove the housing by gently sticking a pin under the plastic tab located on one side of the end of the female connector's housing, either from a male wire or the 2.54mm header pin.

- the trick is to push the wire into the housing so that you can get under the plastic tab

Pictures will make this clearer.

Step 3: Customized Wire Harness

Following your wire diagrams you can make customized wire harnesses.

In the example pictures I made custom wire-harnesses for connecting the nRF24L01 Wireless Transceiver module to the Arduino Pro Mini.

Nice idea - very professional.

A quick and effective, if slightly less elegant, method is to make the connections using wires from the 40-pin DuPont strips and then run a little super-glue (low viscosity) along the backs of the connectors. Wiggle them slightly to work the glue between the individual connectors before it sets. They will set into a solid block in a few seconds.


Thank you for your most excellent suggestion! It's a helpful additional to this topic :-)

That makes everytihing look very clean and profesional.
