I have a blinkt pHat that covers the entire GPIO pin array and I’m trying to trigger changes to the LED array after an external prompt. I expected to use a momentary switch connected to the GPIO pins, but the blinkt covers all of the GPIO pins … is there another set of contacts I can solder some pins to and create an additional spot for a switch, or is there a way to stack headers in such a way that I can “tee” into two pins, or otherwise access two of the GPIO pins?
This is on a pi zero w if it matters.

Hi @user3.1415927, Ah, let me see. Yes, there are spacing saving breakout boards they fork all 40 pins to two pairs. And if space is not a problem, you can use a ribbon cable. See my picture: raspberrypi.stackexchange.com/questions/99339/… – tlfong01 6 hours ago

You could just buy the accessory Pimoroni sells for the purpose. – Milliways 5 hours ago

I was hoping to not use a ribbon cable, but rather looking for a safe way to tap into a header as it rose up … another stacking header I suppose. – user3.1415927 5 hours ago

Or you can unplug the male to female duPoint adapter from the HAT, and replace it by any “tappable” or “forkable” breakout stuff you DIY. Seee my answer’s Suggestion 4 – tlfong01 4 hours ago
