What spec hardware?

1

Hey,

Just wondered what hardware spec people generally use to run Anthias. I bought a Pi 4b, but was a little unsure what RAM I should pick, so I selected 4GB. Even the SD card size was a bit of a hit or a miss. 32GB is what I got and I guess this is more than sufficient.

What do others tend to use?

For me I am just planning to display menu/price screens in a fast food establishment. I’m guessing if you introduce a lot of video files then it gets more memory hungry?

Do you generally use one device per screen? I notice this Pi has two HDMI outputs and wondered briefly if the two outputs could be used to display two different screens?

We have a 1 GB Pi 4 which was freezing and became sluggish after running a bit (4k resolution TV, Anthias displaying simple webpage with html slideshow)

Our 8 GB Pi 4 runs well, though the case also has better cooling. But Anthias has taken up 3.5GB of RAM out of 8 GB total!

So that could mean minimum of 4 GB RAM required for 4K Anthias. Maybe unless Anthias is more liberal with RAM usage when it knows there is a lot. Does Anthias compress RAM to run on lower RAM Pis? (therefore allowing it to run on PIs with less than 4 GB Ram?)

  • For Raspberry Pi 4, I would recommend devices to have 2GB RAM or more for non-4K use.
  • If you’re planning to have your Pi play more videos, I would suggest to have a Pi with more RAM.
  • You could try installing Anthias on a Raspberry Pi 4 running a 32-bit Raspberry Pi OS.
  • If you’re going to install the balenaOS version of Anthias, 4GB RAM would be a good minimum for 4K playback as it only supports 64-bit.
