Hi

Yes, that could work, just remember to order the 5v edition ;-)

Cheers

Thank you, that is very inspiring... I am thinking to do the same but for 3 x 5V, but the 3x5V LT1963's I can find are only 1 or 1,5A. Would you know if there is a solution to this? Would like 2,5 or 2A per channel, or at least some of them :)

Also, can you with your solution fine adjust each channel seperately, for example to 5,1V? And - do you know if it is 100% certain that the channels cannot influence each other?

Hi, finally I did attempt to use the regular plug psu to feed the GPIOs.
Now, I have a Hifiberry DAC+ on top of them, so I released it, pluged on the wires and re-installed the DAC ontop.
First, power was on but Rune was not loading. Rebooted, this time Rune came up. I then started a play, but after a few seconds the playback stopped.

I removed this for now, but is it related to having the DAC on the GPIOs ?

Try to connect the power directly to the P3 on the dac - that will also feed the rpi.
