As far as I know there are no mistakes on PCB4, I'll have a look on PCB1 during the next days.
ah cool - thanks julius. PCB4 is pretty basic (power in: that's all). PCB3, i know for a fact that the level-shifting is missing on microsd. VREFTTL may be anything from 1.8 to 3.3v, depending on the Card (which provides 350mA VREFTTL)
