The Pi 5 isn’t very low power at full tilt, but it’s much slower than any of the x86 SBCs from the last few years. There are at least two SBCs that have N100s

The Pi 5 isn’t very low power at full tilt, but it’s much slower than any of the x86 SBCs from the last few years. There are at least two SBCs that have N100s and an RP2350 or 2040 onboard that can do you gpio, and at least one that has native GPIO. I have a Radxa X4 and it runs Arch great (only downside is the crappy stock cooler, no cases, and the unfortunate Pi B form factor).
