If somebody interested look at attachments.
I did not look closely, but some of the resistors seem to have a very small footprint…
Yep some are 0204, which is rather uncommon. Also the crystals don’t seem to be standard HC49.
Altitude, Are there any plans to make a few of the 4 X IIC PCB’s for the SEQ? If not, could you make the design file available so that i could have one made for myself?
Many thanks!
Since the case is hold right now, my seq work has been bumped to the end of the queue but, yes, I do plan on running some boards next time I am making circuit boards (this month for sure).
Altitude,
Bump #2 on the 4 X IIC PCB’s for the SEQ. Any closer?
Many thanks,

I’ve pretty much shelved this pending the case. I did attempt a run of boards however, for whatever reason I had a batch of ultra thick copper boards when combined with my old developer resulted in a big mess with no good boards.
For anybody following, be careful on the pinout for the DIN8 socket. The 1-4-3 layout originally suggested is much more common now and Mouser’s datasheet for 806-KCDX-8S-S2-PS is (at this time) incorrectly shown as 2-3-2 3-2-3.
RS #491-049 looks okay, one has to buy 5 at least where I’m looking.
It seems that Reichelt no longer stock DIN8 PCB mount…
holy zombie thread (last post was 4 years ago). Everything has been long sorted on this and smash has boards
Sure, but is there another relevant thread for the quad IIC? I just wish you’d stuck with the original footprint :). Personally I’ve already bought the wrong part several times; I think RS might have also ‘replaced’ their 3-2-3 with a 1-4-3. In any case it would be good if any future PCB runs could have a dual footprint.
How ‘relevant’ is the quad IIC at this point in time? I thought it was pretty much replaced by the Midi IO module.
Still relevant I feel. Mostly for the BLM, but also for older Cores, to gain 4 MIDI outs or if you don’t need/want the MIDI ins.

Another reason that it’s still relevant is that it provides 5v midi outs where as the MIDI I/O module has 3.3v midi outs.
I found some gear won’t play nice with a 3.3v midi signal.
Hmm. I still have the files for the version I did before Smash did his.. Maybe time to touch that up with a different 7pin connector?

Eventually I found the correct one on eBay:

(BTW, 8 pin connector!)
or not 
Good find

I’ve bought these connectors from this seller before and the fit the 4 x IIC PCB perfectly.
..
Heh, again it’s an 8-pin connector!
This is the one I’ve bought for my cable:
Mouser: 523-T3504-001
It’s very nice, but a bit pricey. And with the above mentioned DIN-8 ;) socket, you have to remove the screw collar to get it to mate properly :roll:
duh. keep thinking 7 pins for some reason
