I got my pin headers from Reichelt.de - thanks for the mouser link, i will check it.
Meanwhile a frech set of pictures:

I found some problems - the DRAM is to large so it is (without reworking the pinheader case) not possible to solder a pin header in the adjacent row. Also in the corner where G#14 and GND are positioned the gap between them was designed to small on the VoCore - you can only solder one of the two pins. For the DRAM problem i might just cut a bit of the case of the pin headers so that they are getting smaller. Also there are collisions of the pin headers with the USB socket, but cutting the pin header helps.
