Hi Arduino People,

where can i find the schematic and the board layout of the arduino uno r2.

I bought a new uno r2 in the hope i could modify this open source hardware but i can't find the documentation.

So please provide a link to the eagle files.

Thanks,
Mic

Did you look in the Hardware section on the Main Site? I would expect it to be there.

Hi CrossRoads,

yes of course.
At the main site and hardware index there is only a link to the R1 sources.
I'm looking for the R2, who has the '8U2 turned by 45° and 4 additional solder pads.

Ah.
I wonder what happened to the UNO SMD? That used to be there too.

But no answer from admin/moderators.

Anyway m2ic, I downloaded it when it was available. I've uploaded an attachment.

Sorry to bump an old topic. But are reference designs final? IE can i convert the eagle file to gerber and get it manufactured?

I am currently in a PCB class at my university. The instructor wants us to learn how to place components, traces, vias, etc. So far i have downloaded the rv2 schematic and used the "to board" command on Eagle to then start placing the components myself. Is there anything i should avoid or make sure to do? I was wondering about the spacing between the I/O so that it can be shield compatible.

You can download the eagle files for any of the arduinos. delete/ripup all the parts except the connectors & go from there.
Then board dimension & placement will be corrert.
