So next questions:
...are these pads the same as the connector on the side, or have we got access to a second USB connector now?
...is the +5V restricted to 100mAh like the OTG socket?
...and can we create our own peripheral back plates with spring probes to USB-A?


I don't think software switching would be a problem for users. But having to swap backplates all the time (if you wanted to plug it into a PC) would be irritating.




Peripheral back-plates, here we come!
