Quectel RM500Q

Mechanical

This is a 5G module in 3052 form factor. The length of the m2 slot of the ngff-breakout v2 unfortuantely is too short to properly mount it, but with a bit of adhesive mounting tape, it can be made work. See #4782. We will address this in a subsequent version of the ngff-breakout board.
