I’ve burnt a whole day trying to diagnose things. Finally did a sanity check checking if each pin actually was right. Found that the documentation is wrong.
The image that shows the new pins for the xiao nrf52840 plus is wrong.
1.03 and 1.07 are SWAPPED.
I’ve confirmed this with the kicad files.
It looks like it’s only these two pins.
I hope this saves people the hours of troubleshooting it could cause.

Hi there,
and welcome back…here.
So cool you even got one, I’m waiting still.
Ah’ the pain of early adopters, we suffer in silence until now
good catch btw, I’m of the opinion they should have developed the connectivity first. socket, or edge connector dense enough to support those extra castilations… 
I’ll have a video of the innovative test socket(Xiao Clip Base) coming up soon.

Hi Alakuu,
Indeed there is a inconsistent in the KiCAD file and PCB schematic as you suggested, we’ll fix this issue.
We appreciate your feedback!
