I am aware that all the pinout diagrams for the XIAO series on our Wiki are currently unsatisfactory. The images fail to directly show the mapping and accessibility of various pins across different platforms.
Oftentimes, users have to hunt through code snippets or schematics scattered throughout the Wiki just to identify which pin numbers should be used. This has caused a great deal of frustration for everyone, including our own team, when developing applications.
I spent a significant amount of time redrawing all the XIAO pinout diagrams. I’m posting a preview version here for everyone to take a look at.
If you spot any errors, please send your feedback to me. I will update the official documentation with the corrected versions later.
I hope this helps everyone. Thank you!

I really like and apreciate all your hard work
Only one comment, not a request for change… especially if it is alot of work
but… I find the A1-yellow & D1-Green is redundant and a little waste of space
I UNDERSTAND not all pins are analog capable, an a distinction needs to be made
It seems like a waste of color and real estate in this area
I notice in this example the ADC#0, 1, 2 is identified, nice touch
Notice this rough edit /example
not sure if this is an error the usb d+/- does not match the silk screen here…
again I am not an expert… and i am sure some of these pin locations are for backward compatable with XIAO expansion board.. but why are these pins not in a standard location on the bottom of all XIAO form factor?… is this something we can explain the reason/modify the XIAO Expansion board / standardize for future revisions… just thinking as a detail engineer… I do not really use or know how these pins work… FYI/IMO
