I have used Roon since several month now and I want to try Ropieee on a Pi3 that a friend lend me. I use some DAC USB on it as E1DA 9038S or Lotoo S1. I use also a power bank to be more power free.
It’s working very good. But I have several (newbies) questions.
Is a Pi3 is enough for Roon or a Pi4 will be better (for what I don’t know)?
Will it be other screen supported in the future? For me and my use, the 7" is too big. I want more a portable thing (and it is sad that Roon Android app has the android limitation…)
The wifi transmission between the computer (with Roon core) and the Pi3 is without any loss of quality?
This is my portable unit using a RPi4 with a Dragonfly Cobalt DAC. It is mounted in a Smarti Pi case with a 7 inch screen and is battery powered. I think the RPi4 might have better WIFI capability. I use mine with Sony WH-1000XM3 headphones and it sounds great.
I have two Pi4’s running Ropieee. They run at 41°C and 55°C respectively i.e. 20-35°C over ambient. Cooler Pi is in an Argon Neo aluminium casing where the casing acts as a heatsink. Warmer of the two is equipped with a HifiBerry Digi+ Pro HAT in a HifiBerry steel casing with no additional cooling whatsoever.
Pi4 running hot is less of an issue (runs 10°C cooler) since latest Raspberry firmware updates. Also Ropieee is not as CPU intensive as some other applications might be.
This exchange made me paranoid enough that I ordered some heat sinks with thermal tape for my DigiOne Signature setup. If my Shanti PSU ever decides to show up (thanks DeJoy) my Pi will be running 24/7.
