@manuti-manuti Well, I take that back... they had actually arrived in yesterdays post so they had actually arrived when I wrote that I was expecting them!
They look really good. I had also ordered some breakout wings which just do the conversion from 2mm to 2.54mm. So I now have the option of straight-out breakout adaptor (which should be be very breadboard friendly as you can have the wings go under the Omega2 and make more of the breadboard accessible) or a quasi dock with USB power and a serial connection. Nice! Just went and ordered a load of bits from eBay to populate the board... hopefully I got all the right bits!
