Got my board. The regulators appear to have some solder bridges. Are these normals:
I can't see your pictures. But all PCB has been tested before it is sent out. The 110V/220V selector switch can be welded with copper wire.
Soekris is planning new firmware for the dam. Is there a possibility that the AZ kit needs firmware upgrade also then? If so - how is this done?

I am interested in your dam1121 SK lite controller.
You wrote besides the controller, the power supply will also be able to supply 5V (400ma) and 3.3V (200ma).
This fits exactly into the requirements of the DIYinHK "XMOS 384kHz USBtoI2S" board and the digital part of the dam1121.
If so I would always use the power supply to 100% capacity. Is the power supply designed for this? Does the power supply still have reserves?
I actually like the concept of the oversized power supply. For example, my power supply of the analog part is several times oversize.
Following this I would have to use an additional, separate power supply for the dam1121 and USBtoI2S board.
What is your recommendation?
I am also interesed in your answer regard this question ;-)

I don't think it's a problem. Soekris is just upgrading the official digital filter, and it doesn't change the way of control.
@fred sonnen
It's just enough. If a few times power redundancy is needed, additional power supply is recommended.

Hello Audiozen,
What do you mean that in AZ1021 SK module Dam 1021 is not included?
What do I get for 169 USD?

Robert

I have a question regarding the power on precess:
Beside the SK lite I will have a dam1121 and a DCG3 PreAmp within one case.
I will use the SK lite PS for the digital part of the dam and the USB card. for the dam analouge part and the DCG3 I will use 3x SSR03 Power suplies pcb's. I think together not more than 30VA.
Am I right that the "Rotary encoder" is also the power button for the SK lite? Is there a kind of process done, when hiting the "Rotary encoder"?
I think I have to use a kind of power switch. The idea is to use one switch to power up the complete box (dam1121, SK lite and DCG3).
Is this possible?
Is there anything to consider?
If this is not praktical what is the best sulution?
The encoder is not a power switch, and our SK and SK Lite can't control the power switch. It is simple to use a mechanical switch.
Hello,
Do you still working on a dam1121 boards ?
Also i see in the product description that the screen can be turn off. But do you have a screen-saver function ?

The dam1121 setup motherboard is still in progress, and the schedule is slower than expected.

Here is promised updated version of CAD file prepared for aluminum case WA50 (availible on Ebay or aliexpress) -box size 308*320*70mm
important : there are two important layers in this draw
"0" contains main openings (there is also RPi streamer openings you can easly remove)
"PRINT_Engrave" containing vector fonts and frames you eventually want to print or engrave.
View attachment New Soekris.zip
I used draftsight freeware tool to create it.
I decided to redesign streamer location to have I2S wires shorter
here is my audiozen pcb during preparation

If i see correctly rpi and Amanero i2s are switchable so you can listen to both inputs. I read something about jumpers to be soldered if you use Rpi. In that case Amanero is not possible to use? Thank you.
