I am prototyping a Wi-Fi thermometer with an ESP8266 and an HT11, it works on the breadboard (!) and now I am designing a 3D printable cabinet. I would like the final thing to be completely dis-mountable, so I am avoiding soldering.

The ESP8266 and the HT11 come with pins that I need to connect. I can use female-female jumper wires, but the standard sizes (I see only 10 and 20 cm on sale) are too long for me.

Any suggestions on how to make a a short female-female jumper cable? I'd say I need a 2 or 3 cm long cable maximum.

    Sorry, but this question is simply about cable assembly and not IoT. But what you need is just a couple of simple wire, crimp and connector case, like these: 2-4 pin dupont connectors. These are called dupont connectors and here is a tutorial if you need one. tutorial. Dec 27, 2017 at 13:10
  • I'm voting to close this question as off-topic because it is a generic electronics prototyping question rather than a question about the Internet of Things. Dec 27, 2017 at 17:03

    thanks a lot for this input! I missed the fact that these are ordinary 2.54 mm Dupont connectors, now that I know their name a whole world is open ...

  • about closing: ok if is OT, but was tagged as hardware in the old fashioned meaning of the word.

    Tags are used to narrow the scope inside the topic of IoT. hardware exists on half a dozen stack exchange site I think, yet your question would be OT there. Dec 28, 2017 at 13:41
