This is an example of what happens when your wallet is bigger than your imagination.

I think its another symptom of the problem of there not being a clear way to get from your smart brainbox which you run a proper operating system on and do heavy computation on to driving lots of motors or similar. There are options, but there's not one that everyone defaults to and you can get good information on.

Weird take. The Raspberry Pi Zero 2W would have seemed more like the natural comparison rather than the Raspberry Pi 4 or 5.

I find it more interesting to think of the Arduino Uno Q as a Raspberry Pi Zero 2W but with 2GB / 4GB of RAM and even lower idle power than the other options with that much RAM. That makes it intriguing as a very low power always-on headless server with GPIO as a bonus.
