Intel CPUs didn’t have proper GPIO, I2C, SPI baked in…
Mayhaps Intel didn’t see the need
(profitability) in such an undertaking. When you have a Raspberry Pi Zero 2 W, with community and documentation settled nicely on the market, one does not simply undertake such odds.
they can get that without changing their architecture and also…
I’m certain that the market isn’t eagerly waiting, with bated breath, to purchase x86 SBCs just because GPIO is included in the package.
ARM (The Raspberry Pi foundation specifically) currently has the momentum in that market. When you want compute, you x86. When you want to signal the thing that computes, low powered ARM SBCs are currently the jobby.
In 10 more years we'll have an update on this update. Pine makes some cool SBCs but I'm not sure how much of it is usable.
