[hpsdr] Ozy_Mini

[Gerd Loch]

Hi, 

I intend to make a new design for an Ozy_Mini which leaves out all
unnecessary components which are now on the board and change some footprints
for optimized production.
Furthermore I will add some protection circuits after the USB connector as I
had already boards to be repaired where the USB controller was defect after
a lightning strike.
Maybe the discussion on the speed of the FPGA is another point which should
be considered.
I just startet to draw a new schematic and will then make a new board
layout. So I expect to be able to  deliver the new Ozy_Mini in about 6
weeks.
