Any possibility to add more 3.3v and 5v output? That will be convenience while interfacing a lot of different sensors.

Will check for it tomorrow - I might reconsider the design and give it a proper power supply to supply vocore and I/O devices.

Also add a 3rd pin for GND to the I2C and UART 'connector'. That would be much easier in use.

Yep - i want to add gnd to every function group

The prototype pcbs have arrived - just waiting for pin headers to start testing.

Looks good

Thanks - btw, it is a pain to get 1,27mm (0.100") headers in germany - do you have a good source?

They are a pain to find anywhere...
In the U.S.A, Mouser has some, details for the 4 position sockets are below.
Mouser Part #:
855-M52-5000445
Manufacturer Part #:
M52-5000445
Manufacturer:
Harwin
Mouser claims to have a location in Munich but they may not carry the same items there.
For the others (pins and 7 position sockets) I am getting ones in stock with more positions and will cut them down to what I need.

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.
