Not a full review yet, I have not had a large amount of time to go over.
Schematic
Nice and clean.
[x] Labels/net names for some of the more important nets would be nice.
[x] CAN bus lines NEED to be hooked together.
TODO (for me, the reviewer):
[x] Verify converter design
[x] Check availability/cost/etc. on digikey
Layout
Again, nice and clean. Has a few DRC errors that need to be fixed though.
[x] Not necessary, but a bottom-side groundplane should be added.
[x] Power traces need to be made wider/polygons
[x] I'm not entirely sure what the layout guidelines are for the converters, not really sure what is good/bad for power supply design. May want to look in a little more detail into those.
