Yeah but why aren't there more boards with a built in coprocessor like that given how cheap they are now? Iirc only Lattepanda and the Pi Foundation make these sort of boards, and the former is overpriced beyond any common sense.

Keeping the GPIO interface separate does have its advantages, if you accidentally explode a GPIO pin on an external RP2040 board then you've lost a couple of dollars instead of an entire >$50 SBC.

It doesn't have to take up much space either: https://www.waveshare.com/product/rp2040-one.htm

If USB is involved you can't really make a production ready system with it. At least they could put some proper ZH or whatever connectors for UART that don't unplug when you look at them wrong. That's one of the things they did right with the Pi 5 at least.
