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.

USB¶

It enumeratese as 2c7c:0800, full lsusb see attached rm500q-lsusb.txt
