Renora - SPI

hello, I do not see SPI in the existing Remora - Ethernet topic , so I start thgis one.
I have a Mks-Sbase V1.3 and ask where does the wire labeled 'px.x' go?
(refer to remora-docs.readthedocs.io/en/latest/har...e/SPI/Mks-Sbase.html   figure 1 )
It comes from rpi gpio 25
thx  tjtr33

post it here, maybe Scott will know, it is not entire obvious from the docs, but it looks like hes soldering it to something. Im not very familiar with the LPC boards

If you look at the picture with the raspberry pi and the main board you'll actually notice that he doesn't even have that wire installed

Thanks
i had zoomed way in on that photo
but was not convinced some of those fuzzy pixels
meant I should leave the brown wire dangling

I can try tho

thank you tjtr33
