How do you toggle between programming boards? There are 2 DB9 connectors?
You can connect the board directly with the USB and TTL interfaces. Update Firmware one by one.

My proposal on design phase:
PLS do transformer/PSU part easy to broke apart as somebody may use own PSU or want to shift it in lengh if has case which is not enough wide.

All standard I2S Interface USB cards can be used.
If you need to use 2 I2S interfaces, you need to remove several resistors of 33 ohms(nearby the I2S interface, note 33*3
), so that HDMI can not be used.

This is just a test version. The final version should be divided into 2 parts, PSU and DAC, otherwise the PCB size is too large. And the DAC part maybe use 4 layers of PCB.

I upgraded the firmware and now I cannot get signal to lock. Light on board stays solid when I send signal to usb board, but no output from the dac and LCD says "unlock".

Figured it out. Somehow the connection speed was changed. Resetting it to 115200 had me back in business.

One more SK board up and running, we have power at least.

The LED beside the DC input on the DAM1021 is blinking furiously, I'm sure I have seen mention of this but cannot find it... can someone enlighten me?

Hallo Audiozen


I bought a sk lite.
This week te case for all the items came.
I my case the Rotary encoder cable is a little bit short ;-). I can use it but I have to route it over a 100VA Transformer. Will this be a problem?
The cable for the IR receiving tube is to short. Is it allowed to lengthen the cable?
Or do I need a new cable? What is the max. lenght? How do you call the 3pin connector?
Thr OLED flat cable is long enough ;-) But I have to route it over the 100VA Transformer, too. Will this be a problem?


Greetings
