digital isolators

I’ve got a couple of these boards from diyinhk. I’d imagine they’d work just fine with isolating the raspberry pi from the dac. You’d only need 1/2 this circuit (or board) to isolate 3 to 4 pins. … … e-pcb.html

Anyone try isolating the digital pins from the dac to the raspberry pi?

It’s a cheap tweak, the boards are free you’d just need a single ic and maybe a few caps.

I don’t see it providing any benefit.
