Hey,
I did some experiments with a rpi 5 plugged into the Magni silver.
It worked, and I could talk over serial to the motors, however the RPI seems to draw too much current and consistently shut down due to under voltage. The Pi would it would boot and run, its just when it attempted to do some heavy compute that it would shut down, like starting up a ros process or even sometimes a remote shell.
Just letting you know in case you’re thinking about it. RPi 5 is probably not going to be reliable.
