Mezzanine board designed to remove mesh of wires and feed both PI and DAC independently from single board using standard GPIO, Module B feeds Raspberry PI and Module C1 (or C1+C2) feeds DAC module, Module A used as pre regulator

6VDC/2A power source required to feed Mezzanine. (actually 1 A is enough in most cases, if you don't connect external USB loads)

Module A must always be included?

I think no. In first post is "Module A can be bypassed".

Is it true when I connect LDOs in series (for example module A and module C) then total PSRR is sum of PSRR module A and PSRR module B?

My case:
I have smps which operates on 100KHz. PSRR at 100KHz of module A (LT3086) is 30db and PSRR of module B (LT3045) 78db. Is total PSRR 108db for my case?

Mezzanine Power board for Raspberry Pi
I've been running an RPi source off of a Pi modified with this board to replace the on-board DC-DC switching converters for the last 3-4 weeks. NICE!

IF you want the absolute best SQ you can get out of an RPi sourced setup (at least in my experience... and I've tried a LOT of things), you need to do this to a Pi and listen.

I commented on the various power options I've tried with RPis in this post:

Mezzanine Power board for Raspberry Pi
I purchased one from website ... seems to be held up at postoffice in Cincinnati for an unusually long time ... my tracking says it arrived in NYC 7/1, made it to Cincinnati regional 7/6 ... and then "in transit to next facility" ... are they trying to figure out what it does or should I just be patient?
