Hey guys,

    I'm new to arduino and just bought an uno r1, I'm wondering about the differences between the uno r1 and uno r3. Can I run uno r3 sketches on uno r1? And is there any big differences? This will really help. Thanks!  XD

Consider them the same - Minor differences on design - but totally the same functionally.

Biggest change is the extra diode from reset pin to +5V, supposed to keep reset from causing lockups.
