Male/female pin converter?

madbilly

Hi everyone,

First, this is my first post in element14 so I don't know if there is a better subforum for my question - if there is, then mods please move it there.

 

I'm trying to find some pin converters, by which I mean something which will change a male pin into a female socket. This is primarily for stacking shield boards on top of a microcontroller board when I've got the wrong sense pins soldered in and don't want to change them. For example, I have two boards which I want to stack, both have male pins, so how do I connect them? I've looked around a lot of sites trying to find these but haven't succeeded yet and when I was thinking of where I could ask element14 seemed like the logical choice.

 

Helpful suggestions much appreciated.

  • Hi,

     

    I don't think such a thing exists (maybe it does as some hobby item but I've not seen it), but there are a few other options if you don't wish to remove the pin header from one of the boards.

    The simplest is to use jumper wires with the sockets on each end, and patch the two boards. Sometimes just a few connections are relevant (e.g. if the shield board only uses I2C, then four jumper wires are sufficient for SDA/SCL and the supply connections.

    Another option is to get hold of a couple of header sockets, and solder them back-to-back. It would be an ugly solution though. One more way is to build an intermediary adaptor board (i.e. a printed circuit board perhaps), but that's design effort.

    Depending on which side of the board the pins are on, another option could be to use ribbon cables with sockets on both ends. However, this won't always work, because the top and bottom row can become flipped if the pins are on opposite sides of the board. It only works if the pins are on the same side on both boards.

    Hi @shabaz, thanks for your suggestions.

     

    You make a good point about the orientation of the boards, I need to check that I have got them in the right orientation to each other - if not then jumper wires are the only solution. I would prefer to find something which keeps the whole assembly rigid, which is why I was looking for the pin converters, but if I've got the orientation of the boards wrong then this won't work anyway.
