- is it possible to get a part number/reference for the IDC connector?
That's a bog standard 2x11-pin raster-2mm header.
- could you share the IDC to HDMI pinout mapping?
Not sure if I have put that into the Wiki, but we've had that a few days after the MK3 was released in the German part of this forum:
In that thread, you'll see what someone else has designed, and a few hints from me about how to design the board without losing too much signal quality. If an yutomatic translator gives you funny results, you can always ask here; I believe my English is better than Google's 
Been a while and plans have changed; I'm now looking to build a custom HDMI cable that connects directly to the IDC connector on the Mk3.
From the pinouts in the above link I have mapped across to HDMI, but have one missing ground/shield for the clock. Any hints on where I should take that from? And I guess it's also prudent to ask that mapping the shields to ground is the right thing to do?
Also, if I can get a sanity check on the mapping that would be really appreciated!
1,17,19 and 21 are good candidates for that "missing" ground (i.e. not really missing, as it's all the same signal).
The last reply was more than 365 days ago, this thread is most likely obsolete. It is recommended to create a new thread instead.
