Power Filter Board for Raspberry pi

Help and Support
1

Hi everyone,

I’m excited to start my first Raspberry Pi-based Volumio streamer project! My goal is to keep it simple and effective as I am just learning at the moment. I’ve been doing some research and understand that sound quality heavily depends on the power supply.

I’ve noticed some people go all-in with linear power supplies using heavy components, while others simply use the Raspberry Pi’s power supply in combination with a DAC HAT. While exploring options, I came across a Power Filter Board designed for Raspberry Pi DACs, which seems like a cost-effective middle option.

However, I couldn’t find much information about using Volumio with just a DAC HAT and a Power Filter HAT. I’d love to get your advice on this approach and whether it’s a good choice for my first project.

Here’s my planned setup:

  • Raspberry Pi 3B+
  • HiFiBerry DAC2 Pro
  • 7" touchscreen

For power boards, I found these two options:

  1. Option 1
  2. Option 2

I hope you can advise on this setup and how it might affect the sound quality, especially regarding the power filter boards.

Thanks in advance for your insights!

Option 2 works for me

not using both worked for me

the thing is, if those kind of LC filters increase your listening experience- there is something wrong in the chain before

I use option 1.
It works. For switching power supplys it has a greater impact on the sound. For linear power supplies less so.
I installed because it is inexpensive.

Valdemir how do you use this power board (option 2) ? Wat is your power supply ? I have this model Bloc d'alimentation Officiel Raspberry Pi 5 USB-C 27 W, USB-C Power Supply, Blanc : Amazon.fr: Informatique and i can’t make it working.

My DAC is powered separately from the Raspberry by a linear power supply. Raspberry is powered by a switching power supply.
