Arduino Uno R4 Experimenting Bundle

Quand le bouquin sera traduit en français je l`achèterai, merci.

I think its a fantastic kit, but there is no CAN transceiver even thought its discussed on page 302 its mentioned that there is a project for it on the site that side is just left in the wind. , I am aware its not difficult to obtain transceiver but it would be beneficial to have it all together so you can actually do all projects from the book, without having to buyer further items to even do the project! so far that's the only thing I have found to be missing.
