Is there some kind of T-splitter 3-way-splitter etc for pin header blocks? Something that passes through the pins but also contacts them and exposes a set of right angle pins too? So you can use a regular female strip on top (just sitting a mm or so higher than usual) but access the pins from the side too?
For a project I'm working on I have a 40 pin header (typical GPIO, SPI etc block on an rPI) and a board that stacks on top. The top board has a female block pre-soldered on and it's not feasible to de-solder it. I need to access some of the pins in the rPi's GPIO block for another purpose but have very little vertical space to work with. I can't add another full height stacking layer and a breakout board or some kind.
I expected to find sets of pin header taps or similar that formed a collar around the headers and projected at 90 degrees. But can't find anything of the sort.
I'd rather not solder a PCB straight onto the base of the headers and break it out that way. Fiddly access, sensitive components and too easy to melt the base of the pin headers.
There is presumably some "everybody knows" answer I don't know the words for . Help?
