Hello Everyone:
I have been working diligently on my most recent project... and noticed an issue that I hope anyone may have some helpful information.
So, using a 40 pin cable from PID 2029, attached to the header pins on RPI zero w. The other end of the 6" GPIO cable to a 2x20 pin IDC box header PID 1993. Then ultimately I would like to solder the box header to a Proto Bonnet Board PID 3203... but it appears the width of the IDC box header is blocking the GPIO holes on the bonnet, please refer to the attached pictures. I would have to flip the bonnet so the #1 pin matched the back of the zero.
Essentially its an "extension cord". Is there another header arrangement or combination that would allow access to the GPIO soldering holes on the bonnet?
Thank you in advance for all the great help provided.
Sincerely,
The Happiest adafruit Customer

Re: Please help with simple GPIO "extension cord"
I see the trouble you are having with the 40-pin header on the topside. It looks like this was intended more for the header to be attached on the bottom of the perma-proto (like so):
There are a few options for 2x20 Headers that might help you work through this that do not have the IDC box. I'll list those below, but I think the Pimoroni Pico Hat Hacker is the one you want:

GPIO header formats (non-IDC):

Re: Please help with simple GPIO "extension cord"
Thank you for the quick reply and the useful information.
After further fitting and thinking about it, will use the GPIO header PID 2222 that came with the Perma Proto Bonnet Mini kit PID 3203.
The 40 pin GPIO ribbon cable does not seem engineered to be pushed on and off the header on the pi zero, that may be why the IDC box header has the extra support and was made to receive the cable.
I like the Pimoroni hats and phats... adding to wishlist now for future projects.

Re: Please help with simple GPIO "extension cord"
Normally it's female on the bottom or male on top. Or a stacking header which does both in one go.
If you use a stock male header on top, the one you would solder to a Pi Zero, you might just get enough room to access the mounting holes on the proto perma. You'll be able to put two screws in, maybe not standoffs though?
Just make sure pin 1 ends up being pin 1 at both ends. If they get swapped, which can easily happen, pin 1 goes to pin 2 and pin 2 to pin 1, bad things will happen.
I also use a lot of the Pimoroni Mini Black Hat hack3r boards and the pHat Stack.
