Your random thought led me to this one:
A Raspberry Pi that plugs into the a PCI slot, which gives it power and exposes a virtual serial port along with an Ethernet port that shows up on the host system and can be used to route packets to the Pi. The Pi, meanwhile, has all of the usual GPIO things and maybe even an external connector to expose GPIO outside of the PC case.

- bofh23 5y agoNo need to give up a PCIe slot. The Raspberry Pi Zero and the RPi 4 have USB On-The-Go support so they can appear to be a serial port, Ethernet port, or other types of devices using the Linux USB Gadget API. It’s even possible to appear as multiple device types at once.
