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!

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.
