I've several Prototyping kits and Pioneer Kits with different board revisions. I can't find any documentation about the revision differences, it seems that only the documentation file revisions are stated in the corresponding user guides. But no information regarding the board revisions itself in the kit documentation or kit release notes. Even the schematic circuit shown in the user guides doesn't state the board revision.
Would be nice if Cypress would make an overview file for the kit revisions.
