  8. …GPUs, though I haven't read through the whole thread in detail. It certainly looks pretty messy. https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss...
  9. …hamstrings that. Hopefully the next Pi revision has a 4x (at least) lane, like the RockPro64. [1] https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss...
  10. …few addon boards (for $15-30, most shipping after the new year) that take the CM4 that extra mile: https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss... I'm most excited about a few with mini PCIe or M.2 slots on the bottom.
