GPIO Pin or jumper wire size (Standard size is loose) [resolved]

What is the jumper wire/cable size for your male gpio pins? Is it not the same size with raspberry correct?

Respond with a link on amazon that fits your pins please, or give the pin size or your male-pins-part-number. Thank you.


You can keep the dupont cables you already have, if this does not fit tight you can press a bit the end of the cable twith a pair of flat pliers.
If you want to buy something that will work out of the box here are the one I am using for prototyping:


Expansion cable works for me. Thank you!
