Several links to pages on our learn.ubiquityrobotics.com that I have given out on this board have moved in order to clean up how we organize the learn site.
These links such as gpio information, verification tests, troubleshooting, pc board identification and other support pages are now in a support folder.
If you have trouble using a saved link from one of the posts here please refer to the top level index on our learn documentation and use the link in the last section for support.
Top level documentation link (does not change): https://learn.ubiquityrobotics.com/
Sorry if this bump causes grief as it was a necessary cleanup step to organize our internal support of these pages.
