External +5v power source #154

At the moment we have USB on the 48 pin but we cannot feed +5v into MRE via the connector

this is forcing users to power from +12v which is not safe for firmware flashing

is there any chance to allow external +5v into MRE?

Use one of analog inputs to feed USB 5V? Through diode to avoid influence during normal operation? Diode can also be used as jumper - it can be removed if user wants analog functionality only.

how about AV10?

  1. i like that it's on the edge pin on the connector
  2. I like "10" as in "often not used"

we have this on 0.5.0

so far I believe this was NOT tested
