Communication buses
PCIe
Peripheral Component Interconnect Express
The bus used by SSDs, GPUs, M.2 cards. Very high-speed differential.
How it looks
Drawing: this is not on CORE3588, so it is drawn
One PCIe lane. The computer module on CORE3588 has PCIe pins, but this board leaves them unused.
How it works
Where it fits
The fastest of the pair-based buses here, next to USB and MIPI.
