Beware of cheap underperforming clones
As of July 2021 all non-Plus/Plus4 hardware on the market are clones (we have stopped producing V2.2 versions since October 2020), many of which perform badly, and users have reported software/firmware incompatibility. If a clone is selling for much cheaper than the official store ($200) it will likely not meet specifications. See official stores to ensure you get a supported version.

Measurement comparison between V2 versions
We have stopped selling non-Plus versions since October 2020. To avoid getting a bad clone, look for V2 Plus and Plus4 versions only. All V2_2/V2.2 still on the market are clones!

- The V2_2/V2.2 model has reach end of life and is now deprecated. We no longer provide any technical support for clones of this model. The V2 is replaced by the V2 Plus and V2 Plus4 that perform better and are actively maintained. Owners of a genuine V2 from the official stores can contact us to obtain a discount if they wish to acquire a V2 Plus or a V2 Plus4 model.
- You can identify which NanoVNA V2 variant you have using the table above. Select CONFIG > VERSION in the menu on your device. This will show an about screen with the device name on top which you can look up in the table above.
- Ensure the correct firmware variant for your hardware version is used, otherwise your device may fail to boot.
- Only the above 3 hardware versions are official, but some unofficial versions (listed below) also have firmware support.
Unofficial hardware variants
For SYSJOINT's NanoVNA-F V2, see http://www.sysjoint.com/en/content/?144.html
For BH5HNU's 3GHz NanoVNA-F development, see https://groups.io/g/nanovna-f
The following are the unofficial (clone) hardware versions that are tested to be compatible with the NanoVNA V2 firmware.
While we used to allow producing and selling the V2.2 design without royalties, clones from vendors that participate in unfair competition practices such as dumping will not get support from us and are not listed on this page.
Because of disputes about anticompetitive behavior, we no longer permit Hugen/Zeenko from making and selling copies of the V2 PCB design and have issued a public statement in October 2020: https://groups.io/g/nanovna-users/message/17875
The designs have been under a non-commercial license since 2021, so anything still being produced are illegal clones and will have no support.
