Run this while gpsd is running:
        ubxtool -p MON-VER

You will see a bunch of junk, the MON-VER part is the important part:

UBX-MON-VER:
  swVersion ROM CORE 3.01 (107888)
  hwVersion 00080000
  extension FWVER=SPG 3.01
  extension PROTVER=18.00
  extension GPS;GLO;GAL;BDS
  extension SBAS;IMES;QZSS

The above show a plain NEO-M8N that has no flash.
