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!
