Hi all,

I'm looking to connect this button PCB:



I have downloaded and installed on my SD card Tinkerboy's modified Retropie image with built in GPIO controller support: https://www.tinkerboy.xyz/retropie-sdca ... r-support/

I had intended to follow the wiring guide on the above-linked page but was just surprised to see that "Up" should be connected to GPIO04, and "Down" should be connected to GPIO17. https://pinout.xyz/ tells me that GPIO04 is 5V power, and GPIO17 is 3.3v power. None of the other buttons are connected to pins on the Pi which supply power. A couple of buttons are also connected to ground pins, i.e. "B" to GPIO06, "SELECT" to GPIO20.

On the other hand, in this thread: viewtopic.php?t=57 none of the buttons are connected to either pins supplying power, or to ground pins, which seems more logical to me, but I am quite new to this sort of thing.

Should I follow Tinkerboy's wiring guide on the above-linked page?

Many thanks.

the GPIO are as follows.....


follow the diagram and pair it up to which ever guide you want to use....
NOT the order of the GPIO (ie: 1,2,3,4)



GPIO 4 is the 7th GPIO on the RPi (the 7th GPIO is NOT GPIO 7)
(the 4th GPIO is the 5v, it is NOT GPIO 4)





.

Wow, thank you Veteran, lifesaver!
