What is your application, if you don't mind me asking?
Skinny Bob looks cool. Are you going to post a schematic?
I'd rather see by name - so much easier to follow than little green lines all over the place.
If there's anything particular in the meantime you are curious about, let me know.
Could you explain in more detail exactly how the power configuration options you mention in the first post in this thread works?

Hi pico,That .jpg of the schematic is a bit hard to read. Any chance of posting a hi-res .pdf?Roger
Only suggestion I might make is to power the 3.3 vdc regulator from the output of the 5 vdc regulator rather then feeding the 3.3vdc regulator from the Vin source voltage. That way if one was to power the board via an external regulated 5 vdc the 3.3vdc would be available?
It's actually got an auto-power switching circuit using a Schottky that will power the 3v3 VR from the 5V rail, unless there is a higher voltage on the Vin input, in which case it will draw power from that.
