Altitude Posted August 2, 2016 Report Share Posted August 2, 2016 (edited) So it is time to offer a bulk order of these boards. This will be a PCB only set consisting of the DOUT/Jack board and the Aout module that mounts on the back of it. I could also offer this with the liner driver receiver if there is interest for it and possibly a PCB euro panel. The module does this: 3x DOUTs for 8 5V gates, 8 clocks, and 8 Triggers 8x CV Channels via the MAX525 DAC with the Bipolar offset option. There will be an additional DOUT/DIN header on the board for linking to a Euro TPD module down the line The module is provisioned to be powered via 10 pin euro power header with the +5V being supplied either by the module itself or from the line extender. I tested both ways without noticing a difference but do recommend that it be powered internally. Pricing will depend on how many people order but expect ~ $30 for the set of just the DOUT/Aout boards Sign up here: https://goo.gl/forms/1OGckjLWgzbw1sTq2 Also, a warning: This is an all SMD board, 0603 size passives, SOIC opamps, and the MAX525s are SSOP size, if you dont have experience with soldering parts like that, I recommend getting some practice boards off ebay until you are comfortable. This is not a beginner's surface mount project. Boards will be made by PCBway. I can get ENIG plating or leaded HASL. Leaded HASL is much better to solder to but is not ROHS compliant so input would be appreciated on that.

YannickD Posted August 3, 2016 Report Share Posted August 3, 2016 Hi Altitude, I registered my interest via the form but I would really appreciate it if I could get a full set ( PCBs + Line driver PCB set + panel) from you. Especially since you are shipping from the US I would rather pay you more and have everything delivered at once. Don't know if this makes sense to you, but I just wanted to let you know.

Altitude Posted August 4, 2016 Author Report Share Posted August 4, 2016 We will see how it goes. 25 ppl is the critical mass for this. If we dont get there, I'll just release the files and people can get them made where ever Quote Link to comment Share on other sites More sharing options...
Psykhaze Posted August 5, 2016 Report Share Posted August 5, 2016 I've put the link to this thread in the wiki in Modules and Parts >Bulk Order> Running Hope you will have 25 ppl interested. Bests, JK Quote Link to comment Share on other sites More sharing options...
Rowan Posted August 5, 2016 Report Share Posted August 5, 2016 Leaded HASL please. I would also be interested in a PCB Euro panel to go with it. Quote Link to comment Share on other sites More sharing options...
Phatline Posted August 16, 2016 Report Share Posted August 16, 2016 i signed up > i also want a panel+pcbs Quote Link to comment Share on other sites More sharing options...
flyweight Posted August 24, 2016 Report Share Posted August 24, 2016 Hi I am interested, also in the panel. What is the estimated parts price? Would it be possible soldering this parts using a normal soldering iron? I already build the aout-ng without issues. Quote Link to comment Share on other sites More sharing options...
Altitude Posted August 24, 2016 Author Report Share Posted August 24, 2016 the DACs are MSSOP which is fine pitch SMD. You dont need anything high powered but a fine tip is recommended. If you have not done anything like this previously, I recommend a practice board off ebay. The DACs are $22 each so you dont want to screw those up.

flyweight Posted August 24, 2016 Report Share Posted August 24, 2016 (edited) This dac am able to solder its SOIC. Is MSSOP much smaller. If so I think it might be to difficult for me. Edited August 24, 2016 by flyweight updated Quote Link to comment Share on other sites More sharing options...
Altitude Posted August 24, 2016 Author Report Share Posted August 24, 2016 No, its about half that size with finer pitch Quote Link to comment Share on other sites More sharing options...
flyweight Posted August 24, 2016 Report Share Posted August 24, 2016 ah ok to bad but I am really not able to solder such fine components. So I am bailing out. Thanks for your time Quote Link to comment Share on other sites More sharing options...
YannickD Posted October 6, 2016 Report Share Posted October 6, 2016 What's the status on this one if you don't mind me asking? :) Quote Link to comment Share on other sites More sharing options...
Altitude Posted October 7, 2016 Author Report Share Posted October 7, 2016 not even a dozen ppl. We will see what happens when with the TPM but this may just end up as files on the wiki for people to use. Quote Link to comment Share on other sites More sharing options...
Altitude Posted November 29, 2016 Author Report Share Posted November 29, 2016 Ok, this is officially closed for lack of interest. I'll get the files and BOM up on the Wiki. I do have some extra boards from my runs: 2 x Jack/Dout PCBs with one SRIO connector (for anyone not interested in the TPD addon) 1 Stuffed Jack DOUT PCB, tested as working (from my prototype) 1 AOUT euro PCB 1 Jack/Dout PCB with the extra SRIO (for TPD euro) I'll let these go at cost (10$ each for the PCBS, $35 for the stuffed one), first come first served Quote Link to comment Share on other sites More sharing options...
YannickD Posted November 29, 2016 Report Share Posted November 29, 2016 I'd love to get one DOUT and one AOUT pcb. Quote Link to comment Share on other sites More sharing options...
