I hope this is the right place to ask.
I`m looking for a self retaining pcb connector. It should be 2.54mm pitch. Something like this
I have a lot of boards that have unpopulated serial ports, I need to do firmware upgrades over thi port and I am looking for a cable or plug that retains inside the holes when I let go the cable.
I don`t know how this is called or even if it exists.
