Hi Robert,
I see that you usually use variant. But some parts of project (if use Variant) ( like USB part in open rex board) becomes more complicated, board can be conflict power supply or and we must be know more about the function of CPU, schematic also full of risks,design note and time-consuming to check whole schematic. So what do you think?Is Variant is the best choice and why don't you ask your customer for specific function e.g they will use USB OTG and USB HUB (for PCIe and USB stack) so you dont creat future problem?
