Hi DCB!
good work!
Is this layout still latest PCB? Is it possible to get Eagle file for this PCB?

Sorry for stupid question, but that power supply part looks strange - near IC2 voltage regulator, there is C3 capacitor - shouldn't it be between two upper pins (Out and Gnd) on IC2 rather than Input and Gnd?
I looked this layout about 20minutes and still dont figure it out why it is like it is - all other places in internet (breadboard arduino) that power supply part is differently.
Can you comment this please.
