This was incredibly useful in the past; I’d really like to see it make a comeback.
The main advantage of running on a pi compute was that you could access a whole lot more GPIOs, SPI, etc without adding an entire extra device to do communications - in my case, FLIR lepton plus long-range radios running as PPP over TTY devices for inter-swarm and swarm-to-home comms. And having it on a zero was a fun party trick
