@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!

@Keij-H I just order the full 40pin lengths and cut them to suit. You lose a socket wherever you cut it, but you can file and smooth it out enough to make it not look cruddy. Plus it's the cheapest way to get them!

i.e. 10pc 1x40 2mm header for AUD$3.74 including postage from eBay!

Oh, and I have some of those boards that manuti manuti has linked coming (are in the post should should turn this week hopefully) :edit: scratch that, had just arrived!, and they do look really handy if you don't have a dock, and want to shove an Oak onto a breadboard or just have an easy way to power it.

Definetly helpful

But this schematic suffers from the same problem as the one which I presume is for the original Omega Dock... what is that part number (or equivalent) for U1 so we can reproduce the design?

In the case of this schematic, it's D12, D13 & D15. If it's as simple as.. "well, any TVS will do the job"... well that's just dandy... but I doubt that is the case. It is supposed to supress transient voltages... so what voltage should it kick in at? 3.3v? 5v? Somewhere inbetween? It's things like this that will make it more likely that it won't be put in at all, and hence things will go wrong(tm)!

Righty-o... does anyone know where and if a BOM (Bill of Materials) exists for the Omega2? Specifically, I want to know what parts D12, D13 and D16 are on the Expansion Dock, so I can order them if I feel I need them when making my own USB connection to the Omega2. They appear to be TVS Diodes... but what clamping voltage? 4v?

And in my travels, I find it hilarious that in this discussion on Schematics, the fact that the schematic appears to show that the VDD25 always grounded was never fully addressed. Was it just a very dodgy way of showing a single throw double pole tactile switch... meaning the reset line was grounded when the switch was released, and pulled up to VDD25 when it was pressed? I'm thinking the mounting tabs were confused for contacts when the "explaination" picture was put up... and that the switch actually has three contacts, and two anchor solder tabs!
