I was wondering about that, would seperating the digital and analog grounds using 3 pins each on the Euro power connector give any benefit?

<div class="PlainText">The existing IDC connector would have the potential to use different grounds, so this would be a matter of agreeing on a standard and creating a busboard.<br>
<br>
But as a circuit designer I am not sure how much I'd rely on the 5V from the busboard, especially for things like ADC and DAC references.<br>
