        I feel like there should be a simple solution to this, but I haven’t stumbled upon it yet.  The 1.1 version of the Mayfly board now needs a DC converter connected to the USB C port in order to

          You are correct, if you’re using the USB jack to power a v1.0 or v1.1 Mayfly using a 12v source, then there’s no way to interface the Mayfly with a PC for programming or viewing serial out
