oh heck, that's a bad feeling i know, i've hooked up 9v to a 5v sbc before. best you can do for starters is get the datasheet and/or schematic and as powerful a magnifying glass as you can, like a 10x or 15x and spend some time just looking at it for burnt or exploded components. if you got a good zoom camera take a few good close-up shots of each side of board and post them here.
