Right. Another question ^_~
I've been poking at the schematics and it appears there's space for a 5V regulator circuit on the lower right of the board.
In the Schematics PDF there is the CCT diagram for this with a big note under it "Not used. Do not connect"
As far as I can see it doesn't connect to anything other than J8 beneath J7 for the 3V3 selector*.
Is this really the case?
As I'd find it VERY useful to have a good strong 5V source on the board to power arduino shields and servos and the like.
I know 5V is available from the Pi via J24 but that's limited by the Pi's internal fuse and all the current the Pi itself draws.
*Also noticed in the schematics that the 3V3 header isn't so much a power switch. but a selector between the regulated 3V3 and the Pi supplied 3V3 - Just for information if people can find this useful ^_^
