USB OTG Boot
#6
Quote:Yes, micro USB is only used for DC-IN (weird decision in my humble opinion)
Since the A64 SoC only supports one USB host and one USB OTG, they had a choice between having two USB host connectors or having one regular USB host connector and one mini/micro connector for OTG.

Two USB host connectors are useful for plugging USB keyboard and USB mouse without any extra adapters and that's probably what the general public prefers.

Yes, DC-IN could alternatively use a barrel plug. But USB micro connector is the Raspberry Pi approach, which allows to use cellphone chargers instead of a dedicated power adapter. Admittedly this can lead to reliability issues if people start using shitty chargers or bad USB cables.
