When will this show up on the Mini and Dual units?  Is a firmware upgrade to existing mini's possible?

Yes, the firmware upgrade adds CDC interface to the existing HID interface. NMEA messages flow through virtual COM port and HID configuration works like before, independently of NMEA.
I would say in a month or two both Mini and Dual will have the same functionality upgrade.
Thanks to all, Leo

Sorry for bumping a 5 month old thread, but is the firmware upgrade for the Mini still in the pipeline? There's no mention of an update on the website yet.

Leo Bodnar:
Yes, mini GPS clock supports NMEA now.

Here is the link to v1.20 of the firmware with NMEA capability: https://leobodnar.com/files/miniGPSclock-v120.zip

Please let me know if you have any problems using it.

Thanks
Leo

Is / will this be supported on the "classic" (dual output) model?  Looking for an excuse to buy one of the newer models :)

Honestly, given the price point of the newer model, I would prefer it over any "Aliexpress" GPSDO.  I've been very happy with the "Classic" model, and having access to NMEA data is a nice feature.

That's great. Thanks for the link. I'll play with it over the weekend.

I changed the link address slightly as my browsers were complaining about a potential security risk downloading from an unsecure address. So changed it to:-

Paul, "Classic" dual port model NMEA support is on the back burner at the moment. Its hardware is different enough to need extra firmware rewrite to demux NMEA from binary data coming from the GPS chipset.
