Raspberry Pi 4B

Have you all thought about upgrading to the latest Raspberry Pi 4B, perhaps with more memory? Would it be (mostly) plug-in compatible with the existing controller?

Thank you for the suggestion. We have looked briefly at the RPi 4. One problem it that they moved the connectors on the RPi 4 from where they were on the RPi 3, so we can't just change them out without changing our back panels.

Aside from that, we're told that the 4 runs a bit hotter than the 3 and we make every effort possible to keep heat generation down inside the cabinet.

Finally, the RPi 3's seem to have more than enough compute power for our application.

We may need to revisit this in the future if the RPi 3's become hard to get.
