Could someone list the base features that the devices can offer (indicate the differences):

Quote:

Sorry if the question has already been raised before, but it is difficult to find the answer in the thread..
Thanks!

At the usb interface, the spec says:

"J13 is a control signal for an external source if you want’s to turn it off."

What does it mean? Is it saying if there is an external source, then can turn of the usb interface and use external source?

J13 is if you want to use an external isolated power source for the USB...

Hi all.

I have a found a small bug in the software for display/dac. Sometimes it does not show the correct samplerate. I know where the issue is, and the firmware should be running tonight.

Boards are ready to ship out. I just wanted to fix this small bug, before sending it out so that it does not start we a need for a firmware update.

BR

Sonny
