Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

firmware 20201013 hangs on 2.2

Wojtek SP9WPN 2021/05/25 23:55

Hi,

I've just updated firmware on my genuine 2.2 with recommended 20201013
version. Since then I get repeatable hangs when swiping a marker:

Device worked flawlessly on previous firmware (it was 202006... as far
as I remember).

Should I use different firmware? Is it possible to downgrade before a
fix i published?

Thanks,
Wojtek

Same problem here. Think about to go back to a earlier version.

Same problem. I am searching web for previous versions, but not found. It's a pitty that official portal does not have firmware archive.

The only firware history is available, but no bineries.

I recently updated firmware to this recommended version and have same problem.

Has anybody previous versions in collection and provide it to me?

Thank You.

Marcin.
