I have a B+ with an expansion board (3 GPIO connectors), which when I plug a PiHat directly onto either of the three GPIO expansions works fine.
Trouble is I need to take the Hats off board as I’m building a temp display system, so I need to mount the Hats into a case away from the Pi.
I’ve got some 40Pin Ribbon cable, but when I connect it to the Hats (no matter which way round) it don’t work.
My Hats have a Female IDC connector underneath for direct connection to the Pi, I though a M-M ping convertor into a F-F standard GPIO cable (which came with the Pi) would do the trick, but no joy.
Is there a different Ribbon Cable for connecting Hats to the Pi / Expansion that I’m not aware of?
Am guessing it’s all to do with the direction of the ribbon / pins and gender…
Any help gratefully received.
