[quote="ale500"]Regarding the thin traces, you show the top layer of the power supply. Power rails have traces that seem to be too thin. Regarding the switching regulators... you are using National's simple switchers (now TI), the ones that need 330 uH inductors... those are huge in size, your board does not have enough space for them. Try to optimize component place to have stable oscillation. National provides a guide on how to do the PCB layout. Look at the following app note (just an example):
There are higher frequency versions that need smaller inductors (250 kHZ or so).
Maybe not exactly this one, but look at the table Parametrics.

*Edit: Specifically I think this one:

Several of these would fit, granted some topology layouts need to be fixed and Hardware isn't really my forte, most of my time went into the other boards. Not this one. >.< Exactly why I posted this on here.
And Linear Regulators, Examples. Or if you feel like going the extra mile, wanna help me correct this?
and Traces, too small all over, or just on Pwr Board?
*Edit: I have updated and ran the traces larger on every board. And am working on grinding out a new power supply board. New Edits Up soon.
