Sorry Guys,

I know I've personally check this 100 times, but after i made a simple error on my last board i thought i'd check with fresh eyes.

Schematic wise would this look correct? Wanting to be able to have the ability to switch between USB power or an external 5v DC supply with USB connected for data (Futureproofing for higher demands).

having the diodes setup like below and cutting the boards VIN/USB track is all i need correct?. Plus there shouldn't be an issue using the SB120 should there?
