Re: VRM experience and rule R43
The 12V supply and 5V supply in the VRM are separate and independently protected. Issues up to and including a short on the 5V supply should not cause an issue with the 12V supply.

You are correct that it is 2A for both pairs, not 2A each. Last year's VRM was definitely 2A peak, 1.5A continuous on the 5V. Beta teams tested a 2016 version of the VRM, but I'm not sure if the change was to tweak the 5V to actually be 2A continuous or not.

Regardless, at 1.1A continuous you should be fine running both devices off the 5V supply of the same VRM as your radio.
