Vinis a good idea... What aboutVoutfor the other one?VBatis a bit confusing when you're running off USB - it might also imply that it could be an input.My thought was that VCC was TTL+, and VDD was CMOS+ - so probably VDD is the right one for 3.3v? Even so it's totally confusing, and probably 3.3v is the most sensible.
