I think it's time also to release and updated BOM and Parts list.

Neeno did a great job at the beginning with his Document.
but there's some mistakes and missing components that could be already documented.
navigating through the forum, you see the same questions coming over and over again.

I'm doing a new BOM, and would like to release an update to the Neeno document, if he's fine with it.

Are the Mat 12's going to be compatible, and will they require any changes if they are?  Any firm word on the availability date?  I have 4 I'd like to build, as well.
Reformated/updated BOM with Farnell++ parts list
